Reboot loop after Windows XP Service Pack 3 update

"Well, as much as I hated to do this...I ran out of options and needed my computer back.
I installed Windows 7 RC and will have to migrate to the released version when it comes out soon.

Thanks for all your answers, but unfortunately none were able to rectify my specific situation."

There is an issue between xp sp3 and some amd processors that will cause a cyclic reboot. This is caused by an uneeded intel driver that must be remvoed from teh registry. Search google if your stil linterested in resolutions.
