So I had recently built a new computer, and I can play some games alright. But when I launch some games, or even a few minutes into some, it freezes completely on me, examples of those games are CS:GO, Diablo 3, sometimes World of Warcraft. Like the screen freezes at the last scene it was at, but the keyboard and mouse are unresponsive. Ctrl+Alt+Del does nothing, still unresponsive, I have to hold down the power button on my computer to turn it off after, and it turns back on just fine. When I had run stress tests, it passes everything, but as soon as I try a graphics stress test it repeats the same process, I have no idea what this is.
Specs:
CPU: AMD FX-8320 Eight-Core
GPU: Geforce GTX 960
Memory: 8GB RAM
OS: Microsoft Windows 8.1 PRO
If you need anymore info please let me know and I will get it for you.
