START UP

[Andy-N]

starting XP i get as far as the windows welcome screen
then the computer locks up, trying to start in safe mode
(with or without command prompt)it goes as far as
multi(0)disk(0)rdisk(0)partition(1)windows\system3 2
\drivers\mup.sys. after which the computer stops
responding... ive tried booting from cdrom and
reinstalling (repairing) windows, but keep getting the
same problem, any suggestions???????
