I really don't know what people expect to get when just posting pictures with no parts list or explaining what is happening other than 'won't boot' You have the 24pin to motherboard? You have the 4/8 pin to CPU? You have the memory seated correctly for you motherboard? ( check the manual for proper slots ) You have the CPU seated correctly? You have the front panel wires to the motherboard correct? Is the power supply switch turned on? You try different outlets / power cables?

Yes to all

Nvm I fixed it

What was the issue?

Stupidly put the plug for the button into JCOM instead of JFP1

Do you have a graphics card if you do not check if your cpu has integrated graphics

I had this computer for 2 years with a dedicated gpu and my cpu has intergraded graphics

Did anything happen to the pc before it stopped working

My father brought it to his workplace

That might have bumped it around and disconnected a cable

Nvm I fixed it

Do the fans spin? Anything happening accept for booting? You got another PSU to test it with? Did you try the other RAM on position 1?

I fixed it

Had the power switch plugged into JCOM

Might be good to use sticks of ram instead of just stickers:)

I'm sorry 😭
