PC won't boot

[Carson]

I built a pc about 4 month ago, worked great until all the sudden it started randomly shutting off, and when I try to turn it on it will boot for a second and then shut off again, when it first started I would unplug the power and then it would work for awhile but now it won't stay on at all, I've tried replacing the power supply, CPU, GPU, but nothing helped 

could it be the motherboard?

1) Did you remember mobo standoffs?

 

2) Try reseating the RAM

Motherboard or RAM, have you tried removing the hard drive to see if it is an OS problem?

Standoffs are what you screw the motherboard into - it goes between the case and the back of the motherboard to prevent a short circuit. It can destroy the motherboard and things attached to it. I forgot them in my first build and they killed my GPU and pci-e WiFi card.

Oohh, I dont know if I put them in or not, I'll check, I did go ahead and order a motherboard tho, just so that I can rule it out as a problem, so should have an update in a week or so. Thank you

Got a new motherboard, plugged it in and now it works, still don't know how it happened but at least I found/fixed the problem
