Some people have encountered shutdown problems after upgrading from windows XP. This is probably linked to an incompatable program, file or driver that wasn't removed.
Run the windows vista upgrade advisor tool
before upgrading so you can deal with the incompatabilities before they cause problems. If you've already upgraded to windows vista, you can still use the upgrade advisoe to track down the incompatibilities.
Click here to download WIndows Vista Upgrade AdvisorOnce downloaded and installed, it scans your system and alerts you to any incompatibilities, enabling you yo either look for an update or remove the offending item(s) from your pc.
Hope this helped anyone who had vista problems
