Automatic Reboot

Hello,

As of today I was getting some weird activity. My windows firewall automatically disabled. I reenabled it. Then I got a torjan virus warning from AVG and an error stating that win something or other could execute. I wanted to clear up my temp files so I used Windows Optimizer XP and it restarted my computer.

Every since then my computer will boot up, finish loading all of the programs and then I get a BSoD that lasts no more than a second before the computer restarts itself and continues its restarting loop again.

I've tried to look up serveral means to identify or fix the problem with no luck. Suggestions were given in 2004 and mostly mentioned the Blaster virus and ways to remove it but I do not have any time to install anything on the computer before it restarts.

Any help asap would be appreciated. Thanks.
