I have a SATA hdd and an IDE dvd drive. When I replaced the nVidia IDE drivers with windows standard drivers the problem resolved.

I experienced the same issues as many posters with trying to boot, and only getting to safe mode after disabling mup in the recovery console. I restored a registary backup and made repeated changes in the bios, reseated ram and removed the cmos battery, all to no effect.

I finally found a solution by googling my specific mobo and "mup.sys".

I have a Dell Latitude D620 that a user in my office just recently presented me with that was having the infamous "mup.sys" problem. (i know, i know, it really isn't the mup.sys)

I removed the drive and hooked it up to my desktop via a SATA to USB adapter kit. I then ran chkdsk /r on the drive and came up with the results you see at the end of my post.

I then replaced the drive in the laptop, first booted into safe mode, surprisingly it worked. Shut it down, restarted in "normal" mode and it appears to be working fine. My concern now, after having done some exhaustive research, it that maybe the drive is beginning to fail and even after fixing the bad clusters in two files who can tell if it is just going to happen again?

Hope this helps someone! And thanks to all the other posters, well most of you, because some of you can get down right ugly. Anyway, thanks to everyone that posted constructive posts that helped me "fix" my problem.

for everyone that has tried all the hardware options here is what resolved my problem. like everyone else my systems stopped at mup.sys, the last file to load before the prince of darkness windows stopped responding with no additional indication of what the hell is wrong. corrupt registry. thats right the registry had become corrupt so i went through the process of restoring the registry from the repair directory under windows. now it means taking the system back to a very early state but after the restore my system booted, then i went through the hassle of reloading drivers.

this was my last resort and it got the system back online.

good luck

Short words is much better.

Same problem as you folks :o" title=">:o"> :o" title=">:o"> :o" title=">:o">

1.- I removed the extra memory I put of 128 MB 133 Mhz
2.- I enabled the ESCD in BIOS
3.- Turn on computer

and the problem is solved, without formatting, re-install Windows, download drives etc etc

The computer I have is a Pentium III who had already Windows XP working without any problem for almost 1 year until OS begon hang in the Start of Windows.

To be honest I dont think that Windows XP SP2 has the problem, maybe the motherboard (I dont know). Bydaway the computer had already 512 MB (2x256MB 133 MHz each).

I tried also to use a memory of 256 MB 133 MHz but hang again the system.

Cheers

For those of you with multiple hard drives(who doesn't), this might be of interest:
I have a desktop which I rarely use (prefer laptop), however was working fine last time I used it. Booted it up the other day and you guessed it, hung at mup.sys. The only difference with mine is that after a long time, it would finally boot to desktop but nothing seemed to work very well etc. Tried many of the cures on here, but all to no avail. Finally I was going to back up some data from C: drive onto one of the other ones and reformat C: and start from scratch. However, when I tried to access D: drive to copy the files over, the system sat there looking at me for a very long time. Booted to DOS and discovered it couldn't find D:. Unplugged D: drive's cable, and the boot went fine and computer now works no problem. D: drive had died, just like that. So, of course this is no cure all, but simply another thing that people need to check if they think they are having mup.sys problems.

37 pages and counting?!?

Anyway, i thought my system was completely screwed this morning. I wanted to flash bios, replace cmos, disconnect cards, etc. etc. Then i managed to disable mup.sys from the recovery console. And now, everything works fine...

My computer was constantly freezing. It wouldn't even reboot. No BSOD. Sometimes it didn't even make it past bios or post. When it did, it lasted about two minutes before freezing. I don't know what started this problem, but i suppose it could have been a power failure. Anyway, after making it into safemode, i realised that it stops at mup.sys. I saw people on the net saying, that's not the problem, it just gets blamed because it's last to display. Well, i did this, and now i can boot to XP and linux, no crashes, all fine. I did a dskchk, which did its thing, re enabled mup.sys as boot start service, so now it's (hopefully) back to normal.

Why would disabling, fixing and re enabling this service solve everything?

TURN OFF SATA MODE IN BIOS U LAMERS!

teodora miteva — 2008-04-15T08:02:04-05:00

its true, this is a system file and is just a warning that something is wrong with your system, hard drive whatever .... many reasons to have this message.
what i did is to check the disk for errors, i had some bad sectors fixed them and reinstall windows.
disabling that file will allow you to go at least to the safe mode but will not fix the problem.

Again it has nothing to do with that file, I mean he is booting from the good hard drive thats been loading mup from his good drive for months, he puts in a 2nd drive that he is not booting from, is that going to stop his good drive from booting from its mup? No. His system is not using the bad drive mup file, its using the good dive mup file.

You added a hard drive that the bios/os is not syncing with. Just go into recovery consol you might fix it up. Then try to jumper the bios to erase it, which will again force a resync.

teodora miteva — 2008-04-14T08:04:39-05:00

to disable mup.sys you just write -
disable mup.sys or because sometimes gives something like "unknown ...." then is just - disable mup

for enabling it - enable mup.sys SERVICE_BOOT_SYSTEM

Dear all,

Having looked though some of this forum I have another problem for you:

I am attempting to retrieve some data from a friends hard disk. They have the mup.sys issue. I have plugged their HDD into my working system. When I boot the working system, from the working disk, with their HDD I get the mup.sys error.

The aim here is to get at the data on my friends HDD. So:

- Can I disable mup.sys and still boot into windows?
- If I disable mup.sys how do I re-enable it? (Obviously when I remove their HDD I don't need it disabled)

Many Thanks
Jeremy

A lot of these errors are caused by the fact you cannot just move a hard drive from one computer to the other. In my case most of my errors were caused by the 10.3 MB limit on the system hive, in WIN2K, this limitation is not present in XP or better I think.

None the less, this stop indicates a system hive problem. Again stopping at this point (mup) has virtually NOTHING to do with individual files or drives in MOST CASES. If your system hive is proper you will get to the GUI.

There are two free programs to help. One, VsScrub will reduce the size of your registry, use this along with the phantom program to remove "phantom hardware" and you can vastly (I went from 10MB to 6MB) reduce the system hive (this one loads the drivers needed to start). The other is the microsoft sysprep which prepares a drive for a computer with different hardware.

I wrote these notes for myself so they might not make a lot of sense:

1. Clone Disk. Disconnect the source drive. Boot into the clone.
2. Prepare Clone. Regedit Mounted (remove all) HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices. You want to remove all enteries (a lot) in this key to force the OS to get information on the current drive in the system and not use old stuffs, or something.

Defragment. Remove Phantom Devices. Remove SoundMax if going to other hardware. Shut off roboform and currentuser software Microsoft windows current version run, stuff you don't think you will need on new computer. Rename to new computer name for network, set video size to new computer.
3. VxScrub to reduce registry size.
4. Run from cmd line. Run VxScrub -p
5. Hard Shut off computer (don�t shut down from windows).
6. New Computer must have mouse and Keyboard to ps2 or usb.
7. If going to same hardware remove drive from source computer and put into new computer.
8. If going to different hardware boot up into clone drive (don�t install anything if prompted), run sysprep, will hard shut down system.
9. Move drive to different hardware. Will boot into win2K setup (if used sysprep), will need operating system key. Answer questions and load drivers until stable.

To install the mouse drivers for the odd receiver click on the receiver in device manager, do the windows update then do other drivers not the oem83info and the Logitech driver will show.

I guess there are better ways to remove the phantom drivers:

Using the registry editor can destroy your system and those links may or may not have virus in the downloads - proceed with caution. Anyway the above took me 100 plus hours of reading to make, you can also just try some products from Arcronis

http://www.acronis.com/enterprise/products/snapdeploy/

for $30. I didnt use this but it was my next step.

Oh ya, you can get into the recovery console by booting from the actual windows CD, get into the recovery console and just type "listsvc", you don't have to really change anything. Then type exit. You will then PROBABLY get into the GUI on just the next boot up, from the hard drive that stopped at the MPU spot. Just going into the Recovery console causes some kind of resync between the OS and the BIOS or something I havn't figured out. Of course next time you shut down the same problem will reoccur. But you should be able to get into your failed system to do some fix ups, plus you dont feel like you have to lose your hard drive anymore lol...

Also if you dont care about your programs or data just do a clean install, you will save 50 hours of work.

hi,
i have a notebook with Windows XP and linux fedora core 7. the linux part works perfectly fine but with the windows have the same problem as everyone up to now - it freezes at Mup.sys . everything was fine up to now, i had both - windows and linux working more than an year, but now just cant boot windows. cant go on safe mode because it stops on Mup.sys and doesnt go further; because of the same reason cant have any console. i read some tricks but for them i have to have safe mode running. also tried with the recovery disk for windows - also didnt work (well it stuck at some point and didnt go further, so i was unable to continue with it).
any suggestions what can i do ?
