I say this because now when XP boots, you hear the fans and hard drive spinning a full speed and when the XP load screen finishes, the computer gets quieter, but If you found this article on mup.sys resolutions useful (or not) and have comments, criticisms, or suggestions please feel free to drop us a note using our Contact form Thanks! The Mup service is using the mup.sys file that is located in the %WinDir%\System32\Drivers folder. All important files are backed-up, so I am free to experiment.
Thanks again. Even if you don't Im willing to be that is the problem that you are experiencing. If people experience power outtages or someone using their computer routinely powers off without shutting down, errors can become quite common on their drives. mup.sys is the last one it shows.
Now, XP (Home SP1) loads mup.sys and then reboots without a BSOD.

The problem was that even when you power down there is still power going to the hardware (at least on desktop machines) via the power supply.
Booting into Safemode yeilds the same results as trying to boot the standard OS. So now we need to reinstall the old registry files. Then, CHKDSK ran very, very slowly. Apparently, the MUP.sys is not the problem; it's the agp440.sys file which is (obviously) related to the video driver subsystem.

Setting it (mup.sys) to +r seem to "lock" it and its been stable since. Any one of the preceeding actions can end up in the removal or data corruption of Windows system files.
Diagnosing hardware problems can be accomplished with one of the many hardware burn-in suites/tools you can find on the net. If it works, keep in mind that it may not be a cure-all.

Hard drive activity does occur - quite a lot in fact - but the laptop can last for a few hours without doing anything (apparent anyway). KUDOS!

Please note that all comments are welcome and appreciated. Anyway- check the link and maybe search the knowledge base for other agp440.sys problems/fixes... I never created an emergency boot CD (I know, I know) and I am out of things to try so any suggestions are appreciated.

If booting normally it just stays on the winodws boot up screen for at least an hour and then reboots. Everything seems to work! Yet all I get is Mup.sys ???
Of course, the default is to leave them all on AUTO and let BIOS/Windows assign the IRQs. Back up anything you don't want to lose, just in case. share|improve this answer answered Nov 10 '09 at 16:33 Nathan Adams 1,9991319 add a comment| up vote 0 down vote Without a windows CD you might be out of luck. I took the Maxtor out and replaced it with the Western Digital, and proceeded to do a clean install of Windows XP Home.
Type exit to reboot the machine. Was there an association between the mup.sys issue and the power supply or not? Repair installation (but with an SP2 disk) - no solution. This took quite a while so be patient!
To learn more and to read the lawsuit, click here. It then starts these components possibly causing more draw on the power supply. Phew!!! Anyway, on to the problem: I tried to turn the computer on and it gave the C;\windows\system32\config\system is missign error.
