Hello, I have been having real difficulty with my PC in the last couple of days, I will explain everything in full detail to the best of my ability.

PC components *the best of what I can remember
GPU: GEFORCE GTX 660Ti FTW EVGA
CPU: FX-8350 (8-core 4GHz AMD)
PSU: Corsair GS800
Hard-drive: Some old SAMSUNG 1TB
And I don't know my MoBo, but I can probably find out

The situation as it stands

When I booted up my PC about four days ago, I was playing some games as usual, but every now and then, i'd say about 3 - 8 hours apart, both of my screens would turn off and wouldn't turn on again, but my PC fans would still be running, like nothing ever happened. It kept happening so I thought it might be my PSU being faulty.

I took the PSU out, and put it in my friend's PC, it worked for him fine, no crashes over a 2 day period while I tried other 500 - 400w PSU pushovers, and even a 750w (Their fuses all blew)

So, I said it's probably my GPU pulling too much power and I took it out with my PSU and put it in my friends computer. It was oddly fine again, no crashes, nothing. So I took his GPU and my computer wouldn't even boot up at this point, it would switch on like normal, sometimes show the start-up screen and then the screen turned off but still, my computer seemed to still be on.

I took my GPU out of the computer, and left it with only the hard drive, PSU,CPU and MOBO in it. It booted up, I was able to watch about 3 - 5 hours of livestream while it only crashed twice, but it would always restart itself automatically after crashing.

Next, I tried my luck on the hard-drive, I took it out, wiped it and put it back in, put windows on it and such, I left it on while I was doing other things and as soon as I come back to it, it crashes in the same way it has done before.

Now it doesn't even want to boot up into the BIOS menu, inside the computed all the fans are spinning, I hear the hard-drive do it's work but both my screens won't show me anything.

I just have no idea anymore, i'm thinking it's my MoBo, because all my other parts seem to be fine, but I can't test my CPU as I only have 1 mobo that's AM3+ or whatever.

Any help would be appreciated, thanks
 
If removed the graphics card.
And you still had the same crash.

Then the actual problem is relating to your ram modules.
They are either set at the wrong speed or timings, or are set at a slightly lower voltage than they should be.
Or not seated right in the memory dimm slots, check they are firmly pushed in.

You have already ruled out your graphics card as the problem since it worked for two days without error in a friends system. And a Corsair GS800 is more than enough power for the system you have.

So it leaves memory speed, timing, and memory voltage.

Took one stick of RAM out, still doesn't boot but apparently it did earlier but I didn't have enough time to test it fully, will try to alternate the sticks in a bit, to see if there's a change

Also, my BIOS is at default Kapital but it still isn't working ;l
