As my title states, my PC has been restarting out of blue w/o any BSOD or anything. I've noticed it only happens when I've been playing games for multiple hours and it doesn't happen when I play EXCLUSIVELY games launched through Uplay launcher. It's funny because for example when I launch Rainbow Six Siege through steam it has trouble but when I launch through Uplay it's working fine.
I've stress tested my CPU, GPU, and RAM and it doesn't appear that any of those on their own is causing any trouble. I've also tried replacing my motherboard and PSU to no avail. I can't recall any events that may have caused this so if anyone has any ideas that would be greatly appreciated. I can also give any information that might be helpful.
