Computer Goes Black

[xarc]

Hello,

I have the following hardware:

AMD Phenom II X6 1090T
Gigabyte Technology Co., Ltd. GA-880GM-USB3
8.00GB Dual-Channel DDR3 @ 669MHz
2047MB NVIDIA GeForce GTX 770 (EVGA)

and the computer's screen randomly becomes black, the fans spin much faster and I am forced to reboot the computer. Any ideas of what this could be and how to test it?

I ran prime95, ran Passmark's Burnin tests and everything passed fine. I added new heat compound and still this issue continues.

If my current case is anything to go by, it might be the videocard. My computer went black like that before getting to the point where it couldnt POST or boot anymore. I just tested the GPU again today in another computer and it did the same thing to THAT computer. If you can, maybe take that GPU out and put it in another computer to see if its the culprit. If not, try to get another cheap videocard and see if the problem goes away.

To clarify, what are you doing when it goes black? Anything in particular that you're doing before?

The activities are not of any particular, might be watching a movie, might just be typing up a document and might be working on some video work that would require a lot of the video card.

Alright well, the only thing you can do is test. Memtest and prime and Passmark are good but you have to go one at a time with the parts too. If you have multiple sticks of RAM, take em out and test one by one. If you have a spare GPU or onboard integrated graphics, test with each.

Could be a bad power supply, sending an irregular current to the motherboard. If everything else passes and you have another power supply, you might try swapping.
