I have just installed Win XP Pro onto a PC that succesfully runs Win 2000. Now, firstly, I have played around with XP in the past and not had a problem using this very same PC. The specs are:

Athlon Barton XP 2500
512mb DDR RAM (sorry I foget the actual speed)
128mb Nvidia GeForce4 MX 4000
Seagate 80gb IDE hard disk
Gigabyte 7VAXP-A Ultra motherboard

XP runs great until it is time to shut down. It goes well with no error messages. However, once the monitor powers down the hard drive is still whirring away. I've tried leaving it for a couple of hours but it still did not power down properly. As I mentioned before, Win 2000 and XP have not done this before. Now the strange bit. If I move the mouse - a Logitech cordless optical mouse - the drive will then properly shut down I have seen this happen before but it was a long itme ago using an old 6gb drive with Win 2000. I seem to recall I changed a registry setting and it sorted the problem out that time. Trouble is I cannot remember what that setting was.

So, finally, the main question. Does anybody know the whereabouts of the registry power down settings for Win XP Pro?
