sys failure-booting from disks gives usbstor.sys is corrupted

[Trish]

Following a system shutdown imposed by low battery power
now computer fails to boot up at all - aborts seconds
after windows screen comes up - get a blank screen -
occasionally beeps a few times but can't see what's
happening then just goes 'dead'. When trying to boot from
boot set up disks - after disk 2 it gives an error
msg "file usbstor.sys is corrupted - set up failed" and
then just stops.
Any enlightenment would be helpful.
Cheers.

Boot the machine from your Win2000 CD, select Repair
when prompted, then select "Command Console".

You can now rename c:\winnt\system32\drivers\usbstor.sys
to something else in order to disable it. When Win2000 is
active again, you may have to re-install the USB driver.
