Does the BSOD only come from running Windows Update, or does it occur (every time) on boot ?

Did anything else (besides running Update) "change" prior to the problem (new hardware/software, etc...) ?

Start>run>chkdsk /f and hit "Yes" for it to run on reboot.

Start>Run>sfc /scannow & have the XP disk ready.
