Well I just started using Vista a couple days ago with my new laptop. I have Vista HP sp1 (32 bit).
Sometimes, it will not respond at all when I tell it to shut down. It acts like I did not click a thing and the only 2 things that I can do is restart and log off (but cannot shut down when logged off)
This happened yesterday and once today.
I have only put on the following things:
COD4
Xfire
Spybot
AVG Free
ZoneAlarm
