group policy service pack 3 BSOD

Has anyone had any problems pushing out sp3 though active directories group policy. I have a had full of Dell Optiplex 740 PC running xp pro SP2 w/AMD Atholon 64 x2 4050e. Every time i push out sp3 after reboot i get a BSOD "STOP: 0x0000007E (0xC0000005, 0xF79ED8EB, 0xF79ED7F4, 0xF79ED4F0)".

It's a common problem with Dell and HP computers with AMD processors. You need to change the registry setting of "Start" to value "4" in this key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\intelppm
before upgrading to SP3

Since it's already failed, you'll need to uninstall the SP. Directions here for that.
