Thanks for responding howard. I dont know whats wrong with my computer. It all started when I put the sp2 on it. My comp started hanging and rebooting on its on. When I ran the anti virus scan it says there is no virus. when I try to run a registry scan my computer hangs or just restarts it got so bad i had to do a system restore and I'm still having the same problem. I need some serious help pleasssse I'm begging I'm going crazy over here.
