Computer wont boot

[potatosrgood]

I shut my computer down and it wont boot back up. The power indication led on my motherboard flashes but but GPU does not recieve energy. I RMA'd my mother board a week ago due to the same problem. With the replacement motherboard the computer started working but the same problem came back after a few days.

Faulty Ram?

Try booting with only one stick of RAM and if that doesn't work change the slot you put it in and repeat that with other dimms.etc and see if it works

Im not sure. I dont have any extra parts to test, but im don't think that's the issue.Once i replaced my motherboard the cpomputer worked for another few days then same problem. When I press the power button, the computer doesnt not turn on. What I mean is that My hdd, Gpu, etc. don't even recieve power.

Do a cable check then.

Power supply problem?

The cpu fan header does not work either. And why would the power supply work and then randomly stop working? I don't have any extra parts to play around with so, how can I troubleshoot this issue?
