I wish I didn't have to resort to any type of forum, but this issue simply persists.
I built a PC about 2 years ago, and for the last 8 or so months, my computer will restart while playing a game.
It's not only with high-end games, it happens with Minecraft and Unturned as well.
It usually happens after about 3 hours of using the computer, and it'll suddenly crash completely,no warning, no freeze. The computer starts itself back up.
A few days ago, I bought a GTX 1080 because I wanted to upgrade my card regardless, and I hoped it would solve the issue. Now I've been through two cards, so the GPU is ruled out.
After reading up over the last few days, I'm suspecting my PSU may be having issues.
Something I've noticed: Sometimes it will crash at specific points.
For example, when I play Unturned, I'll click Singleplayer, and the MOMENT I hit the play button, it crashes.
When I play CS:GO, it often crashes the moment I load into a map.
However this is not always the case, often times it'll crash randomly. This is ONLY when I play games, happens much more often with Steam games.
After upgrading my Video Card, these are my current specs:
Processor: Intel Core i7-4790K
Graphics card: NVIDIA Geforce GTX 1080
Motherboard: Z97-GD65 GAMING
PSU: Thermaltake Toughpower GOLD 750W
RAM:Corsair Dominator Platinum 16GB DDR3-1866 (8GBx2)
OS: Windows 7
I'm willing to provide errors and whatnot, however I'm not the best with troubleshooting.
I'm considering just taking the gamble and buying a new PSU. I play for large amounts of time, sometimes upwards of 10 hours a day- so perhaps it's blown out since Summer of 2014.
Any help is greatly appreciated ):
