Systems keeps rebooting, mentioning an old temp file I erased a while back. Could be result of bad C

In the past, every once in a while while I'm starting up my computer, it says my CPU isn't working. I go ahead and shut my computer down for a while.

But now it randomly shuts down and reboots. I've searched for stuff with Avast! and CCleaner, and everything, but did not find anything. I've looked it up in various places, and I was wondering if it was the result of the fan. Sounds weird, but thats kinda of what others were hinting at. Help, please.
