mup.sys (1 Viewer)

i'm running windows xp with SP2 and i've been trying to get my system to boot in safe mode but it hangs on the mup.sys driver. ive been searching IT forums for about an hour but unfoirtunately am not that much of a techie myself and dont really understand BIOS and FAT32 type stuff....can anybody explain to my in leymans terms how i can fix this?

"Boot into safe mode with command prompt. Get a copy of mup.sys off of another XP machine. Put it onto a floppy and copy into c:\windows\system32\drivers This will take care of it in 5 minutes or less."

That could be a solution but from what I can see from searching 'mup.sys' on the internet, it could be a hardware problem to do with the processor or RAM. In any case try that out and see if it works.

i dont have access to another pc atm, would i be able to do a similar thing with the XP installation disk (and does it have to be the original installation disk or can it be any)? also, from what i can gather, the problem possibly isnt with the mup.sys file, but the one that loads after it, so would this solution still work in that case?

you cant copy individual files of your windows XP disc.
is this installation with the possible corrupt file a fresh (brand new) installation - or is it an old install and this error has occoured just recently?? If this is the case, its probally more hardware than software - it seems unlikely to me that anything would write to a .sys file and cause it to become corrupt, unless you have a whole heap of spyware etc.
If you trust your self (I dont know what level user you are, novice etc), and you have two or more sticks of RAM in your machine, try taking 1 out at a time, and seeing if that fixes your problem - it might be dead, or faulty RAM - but make sure you always have at least 1 stick of RAM installed every time you turn your computer on.

but make sure you always have at least 1 stick of RAM installed every time you turn your computer on.

Doohh...
Even if you didn't.. the system would still "try" to boot up then it would encounter an error and shuts down.

Don't worry, I'll mail you mups.sys

hmm i've been scoring my own system32 folder and cannot find mup.sys where do they have such weird file? Hypothetically i think mup stands for Microsoft Update.. but usually they have ms instead of m

Well I tried it out yesterday. My desktop computer froze at the mups file like Cholly experienced so I copied my mups from my laptop in the c:\windows\system32\drivers folder onto my desktop computer and voila, it worked, got into Safe Mode.

i spoke to a teacher at school and they said it was a problem with service pack 2... ill attempt to boot it from the installation disk and get back to you guys on my progress
btw JimmyK, the computers been running sweet for almost 2 years so it must be a recent problem, although it could be long running, ive only just noticed it now because i tried to boot safe mode to get rid of a virus...
