I have a rather annoying problem. My PC is rebooting a lot, without giving any BSODs. This happens when I'm moving large files, when playing certain games and sometimes when streaming videos (although this could be due to other reasons and just coincidence). There are no reboots when I leave the computer alone, and I can surf the web, watch videos on my HD, use Photoshop etc.
I recently replaced my power supply and ram due to the computer not booting at all. I had these reboot problems before this, but they were rather rare. For a week after replacing parts the reboots were also very rare, but now I can reproduce them very easily. E.g. the game Borderlands reboots in the main menu after a few seconds. First it would reboot after an hour into the game, then the time got shorter and shorter and now I can't play it. I've monitored the temps of various components, but can't seem to find anything overheating. The GPU goes to 60C+, but that's hardly fatal. I can however play less hardware-intensive games.
I ran Prime95's in-place large FFTs test and I immediately got a BSOD, but even though I had "automatically restart" on BSODs unchecked, it still rebooted, so I don't know what the BSOD was about.
Any guesses on what could be causing it?
- Computer reboots when moving large files.
- Computer reboots when playing hardware-intensive games.
- Reboots might also be linked to video streaming.
- BSOD when running Prime95.
- Rebooting has become a lot more frequent over time (think of a curve with time on x-axis and reboots on y-axis).
- Recently replaced power supply and RAM, but problems existed before this.
- Cannot see anything unusual in hardware temperatures.
