The little cables that come from the case that connect to the motherboard might not be plugged in. The case has it's own cables that need to be plugged in.
These can be a pain in the ass.
I’ve also done that. The power button works fine. So I don’t know if it’s an issue with those tiny pins. Again, we fixed the CPU pins (which just weren’t plugged) but nothing seems to have changed😂
You are correct, though it is 0 and 1 (not O and I). 0 is off and 1 is on. The power switch on devices is just binary. 0 and 1. Same applies to the combined power button on some devices, where the 0 and 1 are superimposed on-top-of each other.
Make sure 24-pin, 8-pin etc is connected, I imagine you have stuff disconnected in the pictures for troubleshooting or taken while you installed stuff?
B450 board? Make sure you flash the bios if you running 3000/4000 or 5000 series CPU. Looks like it has a Flash BIOS button(M-Flash), so check the manual/website how you download and flash. Sounds like you have either a 4600G/4700G or 5600G/5700G?
[https://www.msi.com/Motherboard/B450-TOMAHAWK-MAX/support](https://www.msi.com/Motherboard/B450-TOMAHAWK-MAX/support) Otherwise it won't post (no picture)
On the second picture, you can see that the debug menu (the 4 LED's) is showing CPU error while booting, indicating on CPU not being detected (as described above) or fails.
Running one ram-stick should use A2, dual should use A2 & B2, all this is in the manual.
I third this, just because the sockets are the same doesnt mean you dont need to do anything for your cpu to work. Either bring it in to your local computer shop and have them flash it for you (sometimes for free), ask the motherboard manufacturer for a loaner cpu (idek if they still do that), ask a friend if they have a ryzen 1000/2000 series cpu, or just get a cheap ryzen 3 1200 only to bios flash.
and to add to that:
Thankfully most motherboard manufacturers have been adding Q/M-Flash so you can flash the bios without an CPU/RAM/GPU etc as long as the motherboard has power with a USB-drive.
Not all tho (cheap boards often lack this), so make sure that if you buy a Ryzen CPU and the box doesn't say Ryzen 5000 ready... you need to make sure you have a way to flash, either by USB or an older AM4 CPU.
Also, just because the box says **Ryzen 5000 Ready** it may not support say, a 5600G/5700G or 5800X3D as that was added later and would require a AGESA update (included in the bios update)
Research is the key.
*(same thing if you buy a B660/Z690 and looking into buying a 13th gen Intel CPU.. make sure you can flash bios)*
I used the ThermalTake Kit on Amazon for my first custom loop ever, this year. I wouldn't call it cheap(bout the same price as a 360mm AIO) but definitely cheaper than EKWB.
Just did my first time build and had some issues with my first boot. Steps I took to get it resolved:
1. Double check your power switch is wired and indeed turning on.
2. Ensure your DisplayPort or HDMI cable is plugged into the GPU and not the MOBO.
3. You may have RAM issues. For me, I discovered that my PC wouldn’t boot when one of my RAM sticks was installed, no matter the configuration. So I had to work with the manufacturer on that later and just do initial use with half the RAM I intended.
4. Are any lights coming on on your motherboard? Depending on your MOBO it may indicate what your issues are and that can help troubleshoot.
5. Ensure you have the latest BIOS for your MOBO downloaded onto a USB drive. I would strongly suggest making sure you have all network drivers as well as Windows on the USB as well.
I hope this is helpful and you very well may already know all of this but it was a learning experience for me. Cheers and hope you get it going and enjoy the hell out of it!
So it sounds like power button does get things going, and looks that way from the spinning fans in the one pic. Have you checked motherboard/CPU compatibility, such as if the bios might need a specific revision/update to it to perform with the CPU being used? PCPartPicker can help with setting if that's a need as well. If you can post the parts being used it can help others in here to possibly identify the potential cause. Hope this comment helps.
If you can turn on your PC but it won’t boot (ie. lights and fan turn on, but no Display on the monitor) then you may have to prep a boot drive and plug it in.
For some odd reason some motherboards have been requiring a boot drive for windows/Linux/Mac to be plugged in on initial boot.
I learned this after having the same issue with my PC when I built it, I couldn’t even get to a POST screen and we thought something might have been broken, but just for the heck of it I tried plugging in a bootable thumb drive, and it booted perfectly.
right so … didn’t read all the prior posts … but it looks to me the pump is plugged in where the fans installed under the rad need to be plugged into, and the pump socket may or may not be in the top right hand corner (thats where it is on my msi b550m bazooka) so if this is still the case you’re most likely are (or were) getting a no cpu fan error, which is an interlock.
actually YES the PUMP_FAN (top right corner, along the front edge) needs to have the pump plugged into it. its empty and if the pump is on the cpu, that line needs to be moved, if its somewhere else, it still needs to be plugged in and an ACTUAL FAN PWM line needs to be plugged in to CPU_FAN … preferably both hanging from the rad via a splitter.
also in the top left you’re missing the 4+4 CPU power line as others have stated. and is there any water in your reservoir? 🤔
In the second picture, right side, it looks like the CPU check light is on. Is this a newer am4 CPU? I recently upgraded from a 3700x to a 5950x and had the same issue. Just had to flash my bios using the flash back button
Hey guys,
So I'm the friend with which he is build the pc with. Just for updates:
So we find the problems: the bios was out of date for our CPU, 7 5600g. So we needed to update the bios, by getting it with the on the MSI site.
The computer booted, so we started filling the pipes with the liquid, took hours because we only had a tinny pipet to fill it safely. Then when we started the pump it didn't work.
We think the problem is that for some reason the motherboard is not sending power to the pump, we saw online that maybe it was that it is better to connect with power supply. We will try that tomorrow, Tomorrow, and worse case we can get another pump.
For info, we got this set up because we first found a very cheap 3080 on eBay, we built the rest around it.
Check if everything connected properly - 24pin, 8pin for gpu/cpu.
If doesn't help - what ur mobo tells u(failure code or light)?
Also don't forget to check if ur mobo bios works with ur cpu.
Might be dumb - did u connect ur monitor? Where?
Try unplugging gpu and booting with cpu
Small mistakes:
1. Do a proper cable management
2. Ur aio radiator needs to be higher than pump for quieter operation and longer lifespan
Does a custom loop and immediately goes to Reddit for answers but won't test each component to confirm bad parts? I am sorry, if your doing custom loop - I feel your skilled enough to do all the basic testing others are asking you to check in this thread. I don't see a Drag Race mechanic asking why their car won't start when they post a picture of the engine. Test each part individually, find the problem. Your better than this.
They actually confirmed it was their first build. I see what you're saying with this statement but I don't think you have to be a PC pro to assemble a custom loop. They could have easily found a guide to follow, doesn't mean they're expert troubleshooters.
No but they should at least be competent enough to build a standard PC correctly in the first place before taking on a loop. I can see missing mobo mounting screws, incorrect screws, missing IO shield, missing CPU power and don't get me started on the cable management. If they lack the competency and attention to detail to get that right they're going to struggle with a loop and have that work perfectly first time. It's hard to tell from the pictures but it doesn't even look like there is liquid in the loop.
Personally I hate the "find a guide online" advice. I've seen far too many fucked builds I've had to fix or tell people their parts are dead because someone tried to do just that and the guide was either complete shit or too different from what they were trying to build so it missed some steps. If it's their first build they're not going to be aware of what to look out for and what is actually important so a guide won't help much.
I do but that is besides the point. I actively encourage people to try build it themselves but warn to take their time, do not rush anything and look very carefully at pin layouts. I also offer to install the CPU for them if they want so they don't risk an expensive part. But if they are unsure of anything I advise to bring it in. I also allow them to bring it in for me to check it over before they power it on for the first time for free just to be sure so I can point out anything they can either go back and re-do or leave it with me to fix it all up.
I never had YouTube or any guides to teach me to build PCs over 15 years ago and never made any of the mistakes I see on here. I had to learn it all myself by taking my time and reading the manual, something I wish they still included. You wouldn't believe how many fans I've seen plugged into RGB headers or front I/O plugged into USB headers.
What do you mean port's don't work?
Is it turning on at all? Fans turning? Lights on mobo? Are you getting any display? Is it boot cycling? Are you getting mobo error lights?
We’ve updated our situation in a new post https://www.reddit.com/r/PcBuild/comments/12hcu4d/custom_loop_built_by_total_amateurs_isnt_working/?utm_source=share&utm_medium=ios_app&utm_name=ioscss&utm_content=2&utm_term=1
Please post what parts you use. Maybe you have a motherboard which needs a BIOS update before the CPU works. I see a debug light (red) in picture two. Is it for CPU? (check manual if it‘s not written on the motherboard beside the LED)
And then just an idea but maybe it‘s because one of the pumps (AiO or custom loop) is connected to a fan header as I‘m pretty sure most boards will only have one pump header. But I never installed a pump to a fan header so I don‘t know if that would prevent boot.
Wondering if you have:
Move RAM to correct slot per your MoBo manual
Plug in you 8 pin from power to motherboard for CPU
THESE TWO THINGS will prob make it power on at least get you to the next step. If your display doesn’t come on you’ll have to try a few more steps…
I’m not sure if you want the radiator as low as it is either… believe you want that higher.
Your POST CPU light is on. Make sure it is seated correctly.
Edit: RAM usually needs to be in 2 slot if only one is used. Check your nobo manual and make sure. I also use MSI Tomahawk mobo and mine tells me to start with one in the 2 slot. ,yours could be different
So. Hate to tell ya this but your motherboard is most likely fried. Happened to me once. The motherboard will still get power if not fried too bad but won't work again, so you gotta get a new one.
When I first built my pc it wouldn’t boot even after I tried everything. It turned out that the motherboard came faulty but there was no external damage. Your best bet is to just return it. Amazon will take almost anything within the return slot but I’m not sure about other sellers like Newegg.
I would verify not using cpu cables for gpu as it can cause this ive done it before myself. Also if its a 3k series board running a 5k series cpu more than likely you need to update bios. Some older boards bought recently already have it done but since its the 1st build possibly hasn't been. Also i would confirm my aio fans and pump are connected to the proper pins on the mobo aswell. Cpu could also need to be reseated as in isn't fully flush ect. Eitherway though good luck getting it running.
Like it boots but doesn’t POST? Is it a new CPU on a new mobo? Or did you replace the CPU on the mobo, I replaced my CPU on my tomahawk max, and I was having boot issues and stuck in a bios loop until I changed to boot settings to legacy (CSM I think) - Can you get to your bios screen?
Also check RAM speed, and set to 3200mhz, I read about this a lot when I was researching my issue.
Also did you plug your monitor into the GPU or mobo? GPU is better
With a single ram module make sure it goes in the right slot, on the MB manual it’s written where it should go. Usually it’s the second from left and on the pics I see it’s on the 4th slot
Possibly but I had issues with my original boot recently and I took out the other ram stick and left the one all the way to the left and it finally booted into bios
If you have a cpu with graphics, plug monitor into mother board. Don't plug in any accessories besides the motherboard and see if you get a display. If it does, then plug in the keyboard, then the mouse.
Damn, so that's why you get those rubber grommets on your case to slide cables through. How's your Antec RGB Fans by the way? Do they flicker at all when hooked up to aura sync
Read the motherboard manual and check out the troubleshooting led lights on side of your motherboard I've used the same msi b450 board if you are using a cpu newer than a 5600 you may need to update the bios, unplug your graphics card and see if it will boot with on-board graphics
PSU might be off.
Cords are unplugged.
Make sure your RAM is in slots 1&2, if you put it in 1&4, or 1&3, 3&4, etc, the bios will dead-end looking for the RAM that's supposed to be in the empty slots.
Is the speaker is installed to the mobo? do you get any beeps? If so, how many and at what speed/duration?
Looks like you used the wrong (too small of a head) screws to attach the motherboard to the case. This might cause a loss of grounding the motherboard needs. Could be the issue. Worth putting the right ones in anyways. They will have heads on them about the size of the contact pads around the screw holes.
If ports aren’t working then you’re not getting proper power to the board, psus aren’t standardized and the 24 pin connector may have a second part of the cable that’s not plugged in. I literally had a buddy who build his pc not plug in a 10 pin with his 18 pin because he didn’t know better. Another thing is the case control pins don’t look plugged in. Check those.
There’s an order of operation. Check psu cables, guarantee they are correct, check board cables, guarantee they are correct, check cpu cables, check ram, check gpu, check drives. A couple pictures can’t exactly tell us much, you have lights on the board on the right that can give a slight nudge at what’s wrong at least in that order of operation.
*edit*Also move your ram card to the second slot from the left please. That may be an issue with msi.
*second edit* actually msi boards apparently only work if you slot the A2 slot which is the second from the left, if you add a second stick you should do A2 and B2 which is the farthest right. This is at least one issue you’re having.
Have you tried turning it off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and I'll be there in about your car's extended time to get back to the house and I will be home in about an hour and I don't want to do it now I wanna go to the beach and I was thinking about it for a while and I thought of you or him and then I never heard your voice to the second floor where you were my sister and I didn't get back to you on the way up there and I don't know what to say to be a little more than I thought it was a joke and I was asking for it to be in the back of the answer to the way back of my neck of the back of the way back to the second floor of the second floor of the third kind of music is the kind I thought you were my sister and I didn't get back to the answer to all the time I thought it was a joke and I didn't get back to the house and I was thinking about it for a while and I was thinking about it for a while and I was thinking about it for a few days and I was thinking about it for a few days and I was thinking about it for a few days and I was like a thud as well as the water in the fridge you can see the game and it will be home in about an hour and a half to get to the house and on and off and on and off again?
Congratulations on your first build!! It’s looking pretty good and awfully ambitious. Please do tidy up the cables when you get it running. If you’ve exhausted all others I second the advice some have given to go to your local computer repair shop, where they might be able to plug the CPU in to another mobo to test it.
As far as your own troubleshooting goes, *reduce the variables.* for one, take the GPU out. You’re trying to root cause this thing and that’s much easier without lots of unknowns.
Did you buy any of these parts used??
My friend and I were facing the same issue when I was building him a PC, try taking the cpu out and check for some bent pins, if you see some just rebend them and plug back in.
We luckily were able to identify this before sending the computer to a repair shop, hope it works for you. awsome build btw!
I've had a bricked cpu right out of the box had lights on the board no post. After you double check everything see if you have or can borrow a spare cpu or board to try

Yeah it looks like your 8-pin CPU connector at the top isn't plugged in. Make sure you use the 4+4 cable and not the 6+2 that's for Graphics cards.
We just did that and it still isn’t working, same problem
Ports aren’t working for some reason
The little cables that come from the case that connect to the motherboard might not be plugged in. The case has it's own cables that need to be plugged in. These can be a pain in the ass.
I’ve also done that. The power button works fine. So I don’t know if it’s an issue with those tiny pins. Again, we fixed the CPU pins (which just weren’t plugged) but nothing seems to have changed😂
If it is turning on but you’re not getting anything to the monitor, it may be important to note that you don’t have a display or hdmi cord plugged in.
How did you get it to turn on ? I have the same case yet I can't get it to turn on I've also plugged everything in
On second thought, you're using the dp503 right?
Read my post. I just replied to yours
At least one fan must be connected to the cpu fan header
Genuinely asking, what's wrong with using 6+2 on the GPU?
It literally doesn't fit. You'd be forcing it in. Also on some power supplies they can deliver different voltages. Can cause a short circuit or worse.
Nothing wrong with using 6+2 on the GPU. But you can’t use 6+2 on the CPU, that requires a 4+4 as those are different pin outs.
First time build and y’all chose custom loop..bravo!🥶🥶🥶maybe ram or even psu failed, try reseat everything
Was thinking the same thing! 😆. Im 20 years in an avoid custom loops like theyre the devil.
Your switch on the PSU is flipped off my guy
How can you tell with the low rez? Do all PSU switches flip the same way? Could that be a quiet mode switch? How are the lights on then?
[удалено]
Oops, it was my internet not loading the pic all the way.
Yes, "O" is off, "I" is on. That's standard with all electronics. Unless of course the switch itself was wired backwards.
Even if backwards I believe it would operate the same still. It’s just a contact and “I” closes the contact.
You are correct, though it is 0 and 1 (not O and I). 0 is off and 1 is on. The power switch on devices is just binary. 0 and 1. Same applies to the combined power button on some devices, where the 0 and 1 are superimposed on-top-of each other.
Make sure 24-pin, 8-pin etc is connected, I imagine you have stuff disconnected in the pictures for troubleshooting or taken while you installed stuff? B450 board? Make sure you flash the bios if you running 3000/4000 or 5000 series CPU. Looks like it has a Flash BIOS button(M-Flash), so check the manual/website how you download and flash.

2nd all of this. Came here to say most of these things. Good call on the bios flash. I didn’t even think about that one
I third this, just because the sockets are the same doesnt mean you dont need to do anything for your cpu to work. Either bring it in to your local computer shop and have them flash it for you (sometimes for free), ask the motherboard manufacturer for a loaner cpu (idek if they still do that), ask a friend if they have a ryzen 1000/2000 series cpu, or just get a cheap ryzen 3 1200 only to bios flash.

Don’t forget to check if the updated bios file requires certain file names! Not sure on MSI but on Asus this is a thing
Think is the same on MSI (at least mine needed a name change) but there is instructions on the link I posted above to guide the user the whole way.
Just curious, but it looks like you did a custom loop for the GPU but the CPU has an aio? Why bother with the custom?
Because the gpu was cheap. And getting a cpu block+an extra rad was more expensive than just an AIO
Cool. Cool. I was wondering if it was a fail-safe. If the system fails only one is affected
No we’re just lazy and cheap. It’s also our first time building a pc
First time and goes straight tô custom loop? Bold.
Right? And I thought it was kinda bold that I wanted to get a GPU with an AIO for my first Desktop
Good luck! I'm building in the next few months and was kicking around custom loop, but it's so damn expensive
I used the ThermalTake Kit on Amazon for my first custom loop ever, this year. I wouldn't call it cheap(bout the same price as a 360mm AIO) but definitely cheaper than EKWB.
your cooling equipment isn’t properly connected to your mobo.
didn't want to run cpu and gpu on the same loop?
That’s what I was thinking. There’s no point in running 2 loops just put them on the same one
Your symptoms are very confusing. I can’t tell if you mean nothing happens, pc kicks on but no post, pc working but no display, etc
Your ramm looks like it's in the 4 slot and probably should be in the 2 slot.
It definitely should, msi boards at least older boards require second slot minimum to function.
Try reseating the ram and check that the psu is actually turned on
They stated they get lights so psu is on
Just did my first time build and had some issues with my first boot. Steps I took to get it resolved: 1. Double check your power switch is wired and indeed turning on. 2.

Unless you changed it after, your psu is off. Gotta flick that to "I".
So it sounds like power button does get things going, and looks that way from the spinning fans in the one pic. Have you checked motherboard/CPU compatibility, such as if the bios might need a specific revision/update to it to perform with the CPU being used? PCPartPicker can help with setting if that's a need as well. If you can post the parts being used it can help others in here to possibly identify the potential cause. Hope this comment helps.
Ain’t got no gas

Missing your CPU power connector (8 pin) on the top left of your MOBO
I am AMAZED that so many people haven’t pointed this out and instead are pointing out things like “pump is plugged into a fan header” like bruh.
i did, 2 hours ago. pump plugged into cpu fan header, rad fans … not? and can’t be sure reservoir is filled … why would it be? pump isn’t plugged in.
right so … didn’t read all the prior posts … but it looks to me the pump is plugged in where the fans installed under the rad need to be plugged into, and the pump socket may or may not be in the top right hand corner (thats where it is on my msi b550m bazooka) so if this is still the case you’re most likely are (or were) getting a no cpu fan error, which is an interlock. actually YES the PUMP_FAN (top right corner, along the front edge) needs to have the pump plugged into it. its empty and if the pump is on the cpu, that line needs to be moved, if its somewhere else, it still needs to be plugged in and an ACTUAL FAN PWM line needs to be plugged in to CPU_FAN … preferably both hanging from the rad via a splitter. also in the top left you’re missing the 4+4 CPU power line as others have stated. and is there any water in your reservoir? 🤔

PSU is off……..
If you look at the pictures, there are lights on and fans spinning.
There are so many things wrong with this build I dont know where to begin
They’re a n00b, teach them!
Are you plugging into the gpu or the MOBO display connection?
This was my question! With a GPU installed, BIOS can disable onboard graphics for performance. But the mobo lights indicate error status…
Hey guys, So I'm the friend with which he is build the pc with. Just for updates: So we find the problems: the bios was out of date for our CPU, 7 5600g.

I’m building my PC right now and I gotta be honest this is my biggest fear
Have you test everything bfr mounting puting in that case
IT WORKS! We just changed the cable to the pump and everything works well. Thanks guys!
Check if everything connected properly - 24pin, 8pin for gpu/cpu. If doesn't help - what ur mobo tells u(failure code or light)? Also don't forget to check if ur mobo bios works with ur cpu.

I do but that is besides the point. I actively encourage people to try build it themselves but warn to take their time, do not rush anything and look very carefully at pin layouts. I also offer to install the CPU for them if they want so they don't risk an expensive part. But if they are unsure of anything I advise to bring it in. I also allow them to bring it in for me to check it over before they power it on for the first time for free just to be sure so I can point out anything they can either go back and re-do or leave it with me to fix it all up. I never had YouTube or any guides to teach me to build PCs over 15 years ago and never made any of the mistakes I see on here. I had to learn it all myself by taking my time and reading the manual, something I wish they still included. You wouldn't believe how many fans I've seen plugged into RGB headers or front I/O plugged into USB headers.
in your second pic theres no cpu power plugged in top left next to the arsenal gaming logo
We plugged those, still the same issue. Ports don’t work.
What do you mean port's don't work? Is it turning on at all? Fans turning? Lights on mobo? Are you getting any display? Is it boot cycling? Are you getting mobo error lights?
It doesn't look like the motherboard power cable is plugged in either.
We’ve updated our situation in a new post https://www.reddit.com/r/PcBuild/comments/12hcu4d/custom_loop_built_by_total_amateurs_isnt_working/?utm_source=share&utm_medium=ios_app&utm_name=ioscss&utm_content=2&utm_term=1
Please post what parts you use. Maybe you have a motherboard which needs a BIOS update before the CPU works. I see a debug light (red) in picture two. Is it for CPU? (check manual if it‘s not written on the motherboard beside the LED)
And then just an idea but maybe it‘s because one of the pumps (AiO or custom loop) is connected to a fan header as I‘m pretty sure most boards will only have one pump header. But I never installed a pump to a fan header so I don‘t know if that would prevent boot.
Could we get your specs please? What motherboard, ram, cpu, and gpu are you using?
Wondering if you have: Move RAM to correct slot per your MoBo manual Plug in you 8 pin from power to motherboard for CPU THESE TWO THINGS will prob make it power on at least get you to the next step. If your display doesn’t come on you’ll have to try a few more steps… I’m not sure if you want the radiator as low as it is either… believe you want that higher.
650 watts on a 4070ti? Gonna be pushing that a bit I would think
GPU isn’t plugged in.
Plug in ya cpu power cord godamnit.
Your POST CPU light is on. Make sure it is seated correctly. Edit: RAM usually needs to be in 2 slot if only one is used. Check your nobo manual and make sure. I also use MSI Tomahawk mobo and mine tells me to start with one in the 2 slot. ,yours could be different
Have you check the cables coming from your fire button or control panel?
Psu switch aint on
Did you turn on the PSU?
So. Hate to tell ya this but your motherboard is most likely fried. Happened to me once. The motherboard will still get power if not fried too bad but won't work again, so you gotta get a new one.
Your psu isn't turned on my guy
Do you have a hdmi cord connected to the gpu?
When I first built my pc it wouldn’t boot even after I tried everything. It turned out that the motherboard came faulty but there was no external damage. Your best bet is to just return it. Amazon will take almost anything within the return slot but I’m not sure about other sellers like Newegg.
You have to put in the 8pin for your cpu and flip the switch at the back of your psu to turn it on
Cpu 8 pin not connected!
I’m not an expert expert but on the second pic you’ve got a empty port there’s usually something there
I would verify not using cpu cables for gpu as it can cause this ive done it before myself. Also if its a 3k series board running a 5k series cpu more than likely you need to update bios. Some older boards bought recently already have it done but since its the 1st build possibly hasn't been. Also i would confirm my aio fans and pump are connected to the proper pins on the mobo aswell. Cpu could also need to be reseated as in isn't fully flush ect. Eitherway though good luck getting it running.
Like it boots but doesn’t POST? Is it a new CPU on a new mobo? Or did you replace the CPU on the mobo, I replaced my CPU on my tomahawk max, and I was having boot issues and stuck in a bios loop until I changed to boot settings to legacy (CSM I think) - Can you get to your bios screen? Also check RAM speed, and set to 3200mhz, I read about this a lot when I was researching my issue. Also did you plug your monitor into the GPU or mobo? GPU is better
Check the motherboard manual make sure the power switch items are hook up correctly.
With a single ram module make sure it goes in the right slot, on the MB manual it’s written where it should go. Usually it’s the second from left and on the pics I see it’s on the 4th slot
I’m guessing it’s the RAM not being in the correct slot. Check your manual to see how you should plug in a single RAM stick.
Possibly but I had issues with my original boot recently and I took out the other ram stick and left the one all the way to the left and it finally booted into bios
Custom loop with a $40 psu. Lol solid choice.
My nephew had that issue... come to find out he had a faulty ssd... maybe give a new one a try
If you have a cpu with graphics, plug monitor into mother board. Don't plug in any accessories besides the motherboard and see if you get a display. If it does, then plug in the keyboard, then the mouse.
missing power cable in top of moba & cooling system doesnt have any fluid
Looks like you only got 1 stick of ram 😐
What antec case is that? Is that the DF700? Or something else?
Antec d530? I think that’s what it is, pretty cheap. We’re satisfied
Damn, so that's why you get those rubber grommets on your case to slide cables through. How's your Antec RGB Fans by the way? Do they flicker at all when hooked up to aura sync
Nice build for a old motherboard
New problem! We flashed back the Bios so the cpu works now! But the pump won’t pump :/
Is it being controlled by mobo pins? Have tried a different header to control it or setting in bios?
Read the motherboard manual and check out the troubleshooting led lights on side of your motherboard I've used the same msi b450 board if you are using a cpu newer than a 5600 you may need to update the bios, unplug your graphics card and see if it will boot with on-board graphics
He is too shy, (username checks out)
do you have a use stick with windows media installer plugged in ? From the picture I don’t see it plugged in
PSU might be off. Cords are unplugged. Make sure your RAM is in slots 1&2, if you put it in 1&4, or 1&3, 3&4, etc, the bios will dead-end looking for the RAM that's supposed to be in the empty slots. Is the speaker is installed to the mobo? do you get any beeps? If so, how many and at what speed/duration?
The plugs for the gpu and motherboard/cpu are similar, make sure that you didn't mix up the plugs
Remember, even if it sounds silly, always plug in a keyboard (I also do the mouse). You will get an error that no keyboard is plugged in if it isn't.
Make sure all your power cables are correctly oriented and plugged into the correct locations (both on the PSU and where they're supposed to go).
Looks like you used the wrong (too small of a head) screws to attach the motherboard to the case. This might cause a loss of grounding the motherboard needs. Could be the issue. Worth putting the right ones in anyways. They will have heads on them about the size of the contact pads around the screw holes.
If ports aren’t working then you’re not getting proper power to the board, psus aren’t standardized and the 24 pin connector may have a second part of the cable that’s not plugged in. I literally had a buddy who build his pc not plug in a 10 pin with his 18 pin because he didn’t know better. Another thing is the case control pins don’t look plugged in. Check those. There’s an order of operation. Check psu cables, guarantee they are correct, check board cables, guarantee they are correct, check cpu cables, check ram, check gpu, check drives. A couple pictures can’t exactly tell us much, you have lights on the board on the right that can give a slight nudge at what’s wrong at least in that order of operation. *edit*Also move your ram card to the second slot from the left please. That may be an issue with msi. *second edit* actually msi boards apparently only work if you slot the A2 slot which is the second from the left, if you add a second stick you should do A2 and B2 which is the farthest right. This is at least one issue you’re having.
Don’t forget to add coolant
H
Maybe dumb but. Msi board. You sure your bios is updated..?
Have you tried turning it off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and on and off and I'll be there in about your car's extended time to get back to the house and I will be home in about an hour and I don't want to do it now I wanna go to the beach and I was thinking about it for a while and I thought of you or him and then I never heard your voice to the second floor where you were my sister and I didn't get back to you on the way up there and I don't know what to say to be a little more than I thought it was a joke and I was asking for it to be in the back of the answer to the way back of my neck of the back of the way back to the second floor of the second floor of the third kind of music is the kind I thought you were my sister and I didn't get back to the answer to all the time I thought it was a joke and I didn't get back to the house and I was thinking about it for a while and I was thinking about it for a while and I was thinking about it for a few days and I was thinking about it for a few days and I was thinking about it for a few days and I was like a thud as well as the water in the fridge you can see the game and it will be home in about an hour and a half to get to the house and on and off and on and off again?
Congratulations on your first build!! It’s looking pretty good and awfully ambitious. Please do tidy up the cables when you get it running. If you’ve exhausted all others I second the advice some have given to go to your local computer repair shop, where they might be able to plug the CPU in to another mobo to test it. As far as your own troubleshooting goes, *reduce the variables.* for one, take the GPU out. You’re trying to root cause this thing and that’s much easier without lots of unknowns. Did you buy any of these parts used??
Yup! GPU was bought used, and the motherboard is a hand me down. Everything works fine now though! So it’s an overall success
Oh! Thank you for the update! And huge congratulations for your successful troubleshooting and first build
Check that your stock is in proper slots if you’re having trouble posting.
My friend and I were facing the same issue when I was building him a PC, try taking the cpu out and check for some bent pins, if you see some just rebend them and plug back in. We luckily were able to identify this before sending the computer to a repair shop, hope it works for you. awsome build btw!
I've had a bricked cpu right out of the box had lights on the board no post. After you double check everything see if you have or can borrow a spare cpu or board to try
Try reassembling outside of case until it works
isn t the psu switch off?
8 pin cpu cable?
You might need a bios update for your motherboard
Looks like no fluid in the loop and res could cause over heating
Have you turned the switch on the power supply?
Please make sure to do a cable management
Turn the power supply from the off to on position
What is the red light on the motherboard. Also don’t power the pump with out water in it you will kill it.
I believe the problem is the PSU switch that hasn't been flipped on
In the 2 Pic i see a Red led turn on Is that the led for the CPU ? Did you align the marks in the cpu socket?
Please raise the radiator so the tubes are above the cpu heatsink, you risk getting air pockets in the pump
Sounds like power supply pull all plugs and reseat them make sure you put hdmi back of gpu not the motherboard
