Odds are you have a driver that is incompatible with SP1. Update any older
drivers to the latest and update the BIOS if a newer one is available.
While in the BIOS make sure the power options are set properly for what you
want to do. Did your machine go to sleep first with a switch to hibernation
after a period of time before? or stay in sleep. You should check your
power settings and make sure none of them got reset.
