Hello everyone and thank you for your time helping everyone.
I hope you can help me some this riddle which bothers me so much..

My problem is this: My computer keeps crashing when playing games that require a graphics card. There is no specific time for when the crash will take place, sometimes it will be 10 minutes, sometimes 2 hours.
When a game crashes, the screen turns black with the sound playing for afew more moments afterwards. Most of the times it will go back to desktop and rarely it would freeze the computer altogether.
My rig is a Gigabyte 970GTX, i5 4460, Gigabyte GA-H81M-HD3 mobo and 8 gigs of ram.

Things i've tried so far that made no difference:
- I replaced the PSU with a more advanced and powerful one (600w)
- I replaced the ram
- I tried using the gfx card on a different pc (and it worked)
- I tried formatting the PC and reinstalling windows (tried both win7 and win 8.1).
- Tried several version Nvidia drivers
- Checked the heat, which was fine. All fans are working as well.
- Installed everything on SSD (because why not, atleast i can be sure its not a faulty harddrive).

I'd love to hear any more ideas, questions, thoughts. Please help me play games again!

I had that problem some months ago, and I somehow fixed it. About 4 days ago I got it again, and I think I fixed it again.
My computer is fairly old now, I got a gtx600, so I thought it was just my card dying. After testing it, and more components on another machine, the issue didn't seem to be that related to hardware.

This time it started after I updated my nvidia drivers, so I assumed that was the issue. Reinstalled, rolled back, nothing changed. I uninstalled them, installed them with device manager, and still no change
I cleaned my case, made sure everything is plugged in properly, still kept getting it.
After some messing around, I was feeling that it's a power related issue. Not a faulty PSU, but maybe a faulty wall outlet, or one that has too many things connected on it and can't supply the computer with enough power
I used to have my pc, monitor, laptop and ps3 connected on the same outlet (UPS too)
I moved my pc and my ups to a different one, and since then I don't seem to get the problem anymore. It's been about a day and a half since I've gotten it, it seems like that fixed it.

Your case might be different, I honestly don't know if changing the wall outlet was the fix, or just happened to work

Good luck!
