I have a bad problem with a uncles ASUS laptop which i am trying to help him fix. It has Vista Home premium installed.

The problem is that as soon as i open Outlook, programs start to freeze( Not Responding ). Mainly it is Internet Explorer 7, Outlook and Adobe Reader 9.

It requires me to restart the computer. To get to working again for atleast a while untill it starts to freeze again! It ususally only does it after opening Outlook 2007.
