Mup.sys HELP!!!!!

[Guest]

I cannot start WinXP in any mode. When I try in safe mode the load screen
freezes at system32\drivers\mup.sys. Can anyone tell me what to do??
Disabling mup.sys does not help, it just freezes on the one above it.

Mup.sys is not relevant; it is just the last file to be loaded. Things
are freezing during the subsequent initialisation. Worth trying Safe
Mode - Command Prompt only, and if you can get in with that give
C:\Windows\system32\restore\rstrui.exe
to run System Restore and hope that going back a few days will clear it.
Otherwise I think you are in for a repair reinstall

Alex,

I work with clients who are not computer savvy and just want to get up and
running again. My experience of Repair Install with such users having a
system of any complexity which goes wrong for unknown reasons is that it is
better and likely saves time in the long run to do a clean install from
backup or if the user has - regrettably - not made a backup, do a Windows
clean install to a new partiton of the OS and programmes and recover the
data from the old partition beofre removing it.

The last time I experienced this the cause was tracked down to a PCI Modem
card gone bad.
Dunno if its worth removing any add in cards to see if this makes a
difference. Probably better than having to re install the OS.

I had 'mup.sys' problems after a completely clean install of XP (& SP2).
The PC would run for a while then for no reason just freeze and no reboot
into any mode was possible.

The computer could be re-started by running chkdsk /p after booting from the
CD into recovery mode - no need for a clean install as many forums were
suggesting.

The fix(?), after much hair pulling and head scratching, was to disable the
automatic power saving feature of all the USB devices in device manager.

Bizarre or what?

Wouldn't it be nice to see something from microsoft about all these
thousands of 'mup.sys' problems and why they happen and how to fix them :-/

Dream on.

It is not possible for anyone to list all the "thousands of 'mup.sys'
problems" because as you were told, that's just the last file to get
loaded before the system fails. With all the thousands of possible
hardware/software combinations on PC's, no one could list all the
reasons the bootup might stop there. Troubleshooting has to be done in
a logical, deductive fashion, starting from the very basics and trying
one thing at a time and testing.

This process isn't exclusive to computers with Microsoft operating
systems.

Glad you got your problems sorted, though.
