Instructions

Difficulty: Moderately Easy

Things You’ll Need:

A broken PC

Step1

First if just recently added a new option card or device try removing that to see if it stops rebooting.

Step2

Next clean out all your fans in the power supply and the fans inside your case. Use a can of compressed air. A vacuum works but it doesn't do a good job. Check that all your cables and cards are secure while you have the case open. Push down on all connections, they shouldn't move.

Step3

Scan your computer for a virus. You can use a free scan tool at http://housecall.trendmicro.com
