Windows Update causes Blue Screen BSOD on Dell Vostro 1500 laptop

I am working on a Dell Vostro 1500 laptop for a friend that is about a year
old. The laptop had a virus and caused it to keep locking up and eventually
grinding to a halt. It is running Vista Ultimate 32bit Dell OEM. I erased
the hard drive and wiped it and now I am trying to recover it using an image
made with Acronis True image. I can successfully restore the image and boot
into windows. The image file is as old as the laptop, its the original image
I made when the laptop was purchased.

Vista runs fine until I run Windows update. I don't install every update
available, especially the ones for added features and fluff. After
installing the 44 updates that are found and rebooting, I get stuck in a
reboot loop with a blue screen in between each boot. I tried repairing
windows using the original OEM DVD from Dell, but it wont work. It says
something like there is a problem and we are unable to repair windows... I
looked at the error report everything looks fine except it states there is an
error on one of the drivers and it prompts to uninstall the device or drivers
and try again.

The problem is how do I uninstall the driver that windows update installed
if I can't boot into windows? I am working on my fourth recovery, but I am
still unsure of the update that is causing the issue. I went down the list
and it seems to be all security updates. I unchecked any driver updates I
saw, basically NVIDIA drivers. I am going to manually install sp1 to see if
that will work and then try windows update again... Any suggestions on how
to figure out which update is causing the crash would be appreciated.

Thanks!
