Computer restart automatically

Solution
Can you boot to Safe Mode? Usually you do this by pressing F8 about once a second after powereing on. If you can do that, you can run MSCONFIG, click on the Startup tab. There you can uncheck everything but your antivirus. Something being started when you boot could be the culprit, and that would stop it.

Good luck.
