Hello all, subject line says it all. New HD, formatted and used Toshiba recovery CDs. Windows XP Media Center SP2.

Here are my problems (right now):

It will not shutdown. When I click shutdown, I get an hourglass. It still moves, but nothing else works. No blue screen, etc...Can cntrl-alt-del, but it will not shut down from there either.

It also will not perform Windows updates, either by the icon in the lower left or by the web site.

This PC seems to run normally about 3-5 mins, that it just stops.

Safe mode appears to work normally, with no slow down....

I currently have all Toshiba services stopped, and also all items in startup unchecked. Still happens.

I can provide any other info if needed.

Thanks.
