As the title says, my computer randomly turns off. Sometimes it reboots immediately by itself, sometimes it tries to reboot by itself then turns off again, and sometimes it stays shut off. In the latter case, it doesn't respond to the power button for around half a minute. I've tried unplugging the power cord, waiting, and plugging it back in, but it's hard to tell if that makes a difference.
Normally, I'd suspect a PSU issue, but there are some complicating factors. I recently moved and my desktop could have possibly gotten bumped. Sometimes when it shut down recently it refused to start up all the way, complaining about high CPU temperatures, and indeed after monitoring them it hit 100 C at load and was in the low 50s at idle. (But sometimes it turned off even when it was idling.) I took off the cooler, cleaned it and the CPU and reapplied thermal paste, and the temperatures are better now, and it no longer complains about them, but the random shutdowns continue.
Also, this computer used to have a similar problem before, but it went away after I RMAed my graphics card for an unrelated reason (a loud fan).
