Let's try the usual. Not only do I see the owner take SP2, but accept a driver from Microsoft. That second item (driver) was what I usually find to be at issue.
To recover we roll back SP2 and more to get it working, then we try again...
Motherboard drivers may need updating, but Microsoft doesn't do these...
In closing, you post didn't tell any detail about the machine so I can't comment further.

After installing SP2 a friend reports to me that although he assigns hibernation to the power switch, it does not complete the hybernation The computer stays on. I told him to uninstall SP2 and then follow a certain procedure (spelled out in one of these forum threads) to prepare properly and reinstall SP2. Any suggestions on why SP2 causes this? Frank
