winlogon.exe 100% CPU usage at start up

Hi,

I have a Inspiron 8200 and running windows xp.  At start up winlogon.exe runs and takes up 100% of CPU usage. It cause me not to be able to use my computer for at lease 45 minutes.  I downloaded hijackthis and don't know what to do next. If someone could please help that would be great.  Here is the hijackthis log:
