My Mup.sys problem

For the past few days I have been having problems with my computer...keeps restarting even in the safe mode!!!
Theproblem seems to be some file called 'Mup.sys' loaded during bootup..have tried all possible solutions and still havent got my comp working....must say it know..Win XP is pathetic!!!

It is at times like these that really feel like throwing my CPU: Conked Perfectly Useless device...from the window!!! Well if you guys know ne ideas lemme know...

Thinas already tried:
1. Removing all cards..and memory...
2. Disabling USB
3. Trying to disable mup
4. Kicking the bloody cpu
5. Praying to all the 33 crore gods...
6. Trying voodoo

HELP!!!
