Lately I've been seeing my computer randomly restarting for no apparent reason. My PC was built about five years ago and presently consists of these parts, some of which, such as the Asus Geforce GTX 1080 Strix, are very recent upgrades.
The most recent random reboot occurred tonight when I tried to open the HWMonitor application to check temperatures after roughly a five-hour gaming session of Witcher 3. I had already exited the game when the system abruptly rebooted.
Another time when it randomly rebooted itself was a few months back. As far as I can remember it happened in the middle of a coding session when the system was under very light load.
For each of these restarts there was neither error message nor blue screen; the system merely reboots as if I've issued a normal reboot command.
Since I highly doubt the restarts are caused by overheating (my CPU and GPU temps are normal even under load), could the culprit be my Cooler Master PSU? After all, the thing has been working for five years without problems until now. I've read in similar threads which claim that the symptoms akin to mine are typically indicative of a failing PSU.
