This is an ATI MV2200 card. Sorry about the typo. I was going to install a ATI MV220 PCI card in a friends computer for him. It is going in a HP Pavilion 7850 - 933 Mhz with 512 MB PC100 running WIN XP Pro SP2 - all current updates. I might have stepped on it!!! I uninstalled the Windows onboard video driver before I shutdown Windows to install the card. Now Windows is in an endless booting loop? No matter what option I select: 1) Safe Mode 2) Safe mode w/netwoking 3) Safe mode Dos prompt 4) Last known good configuration 5) Windows normally The system hard reboots after about 5 seconds, over and over again. ANyway to get back into windows without reinstalling?
