Windows comes on after I enter the password and most of the icons usually come up but then whole thing shuts down and restarts. I can run it in safemode, but if I try to change display settings or add/install programs through control panel that also shuts down.
I have run several antivirus/spyware programs and they found a lot of stuff but now say it's clean.
I recently installed a new video cars and though it worked fine for a couple of days I thought that might be the problem so I removed it and plugged the monitor back in normally and there's no change.

here's my log:

after reading post by several people with similar problems I went through and deleted all suspicious programs that were created the day it started, but there is still no change
