Got Worm....Windows won't even Start!!!! HELP!!

[A Mak]

The worm got me. I'm stuck in the reboot black and white
screen. Everytime it tries to load windows, it crashes
again. Windows won't even start at all. Any ideas how to
fix this from this start point?

DISCONNECT the subject computer from any network IMMEDIATELY.

If you are unable to boot at all, a Repair Installation may be
necessary:

Windows Updates will need to be reinstalled.

Then follow these steps:
Install or enable a firewall IMMEDIATELY:

VERY IMPORTANT to follow ALL steps, closing ports or installing the
patch is NOT enough.
Download the patch and regedit referenced in the article below.
You may need to do this at an uninfected computer and burn to CD or
save on floppies.
Each file is small enough to fit on a floppy.
