unresponsive machine

Hi,
I have a pc running xp home. The machine is pretty much brand new (2 weeks old). Before using i installed all windows critical updates and symantec corporate antivirus 10. I created 3 accounts on it.

Now after about a week of use it boots to the log in screen fine. Once logged in the machine comes to a crunching halt. The machine is unresponsive. I can not even get the task list to come up. Not one of the users remembers anything unusual being installed or remembers anything unusual in their emails/ browsing!

I have booted into safe mode

and removed "SearchAssist" from "add/remove programs "
scanned with spybot 1.4 - found nothing
scanned with symantec corporate 10 - found nothing

installed avg 7.5 in safe mode but can not seem to run it. I get the error " Connection to server failed. please reinstall avg "

I have used HijackThis before but i know you guys like to do other stuff before we get to that. What do you guys recommend?

Thanks
Andy

 

ok. sorry to bother everyone.
So it turned out it was spoolsv.exe.
All is resolved
