Lately my computer has been restarting spontaneously during operation. This has happened twice on the same day. I don't know what could be causing this but I am concerned about my computer's well-being. What can I do?

This type of rebooting behaviour is often caused by your computer overheating. You can check your system temperatures with SpeedFan, which should give you an indication of whether your system is running too hot.

Also, I would recommend that you open your computer case and make sure all the fans are spinning okay and that there isn't an excessive amount of dust in there that would impede air flow. See the following Bleeping Computer tutorial for guidance on cleaning inside your computer.

The power of accurate observation is commonly called cynicism by those who haven't got it.

That makes sense. I'll open the cover and blow out some dust. It's just that I've had it dirtier that now and it worked just fine.
