My PC keeps randomly turning off and then immediately turning back on. This happens in various situations, whether I'm gaming or just using the desktop, and it's happened over 100 times now. I've ensured my Windows is clean and checked the temperatures, which are normal. What might be causing this?

It sounds like your power supply unit (PSU) might not be providing enough power for your system, especially under load. Just to clarify, is it just the screen going black or is the whole PC rebooting?
I've had a similar issue before, it turned out that my PSU was the culprit after all. Even if everything seems fine, sometimes they can fail without warning. Check if your PSU is working well.
This could definitely be a power issue. You might want to try using an antistatic wrist strap while you check all your connections. If reseating the plugs doesn't fix it, consider getting a new PSU.
My entire PC is rebooting, not just the screen. Sometimes it even goes black for a couple of seconds while I'm working.
