Help with a BSOD

I have a Dell desktop that is running XP Media center. The computer got infected with some virus’s and I started to get them cleaned up, well when I tried to boot into safe mode I got a BSOD. Then I proceeded with cleaning the virus’s with Spybot and Malwarbytes in normal mode, but then I did a windows update and one of the updates was a video card update. Upon restarting the PC I am now getting a BSOD when booting into both normal and safe modes. What can I do besides completely reloading windows?

Thanks, Bob
