View Full Version : Windows loading hangs at MUP.SYS after SP2 installed

After installing SP2, motherboard drives and changing some settings, Windows will not start on a new computer I have built for a customer.

P4 3Ghz, 1GB RAM, 120GB hard drive, Foxconn motherboard.

Windows XP Pro setup went flawlessly, and the PC started fine, but when I:

- Installed motherboard drivers from Foxconn CD
- Installed SP2
- Set pagefile to none
- Changed computer name

And now the machine won't start. When trying to load it normally, after about 10 seconds the blue bar goes jerky, and then stops and hangs.

If I try Safe Mode, it freezes at System32\Drivers\Mup.sys

It cannot be Ctrl+Alt+Del'd, the Reset button must be pressed to make it come back to life?

What can I do? I want to give the PC to him tonight.

Possibly the wrong video or sound card drivers
Is the sound card integrated or a PCI plugin.
Try another video card if you have no luck with the sound card

Forgot to say this happened to me when I accidently installed wrong drivers for a sound card.
Also how long have you left it sitting at MUP.sys, as I found after about 30mins it would actually continue to boot

Sound and vid card are integrated, drivers are straight from the mobo CD.

Have you tried booting with the last known good configuration?

You should see this option after starting from a reset.

You could also try booting from the Windows CD and choose repair option, but Im not sure how this works after SP2 has been installed.

Oh... well, it would have been about 30 mins by now, but I'll keep it on.

Yes, exactly the same result as normal boot

Trying it now

Can you access the recovery console, if so I can email you a procedure to restore a hidden backup of the windows files from the command prompt.
Takes a while but it does work

With the repair option it takes you to the Recovery Console command line, so unless you know what is causing the problem, ie deleting or replacing a bad file, it may not help.

You could try the Advanced Startup options using F8 key and try booting with VGA mode selected, that could eliminate or otherwise a video driver problem.

Yes I can get into Recovery console.

Tried 'enable VGA mode', didn't work. Same as always.

OK, hopefully 45souths method will enable you to restore a copy of the registry.

Another option is to Enable Boot Logging and look for the file ntbtlog.txt in the root folder. If there is a faulty driver, the last entry may indentify it.

Presumably you'd have to use a boot disk with a test editor/reader on it.

I'm trying your method now, 45south.

Hope your typing skills are better than mine.
As you probably already know, there can be no mistakes, or it's custard time
Good Luck

Damn, it didn't work. Still freezes at Mup.sys, although it is at a different place in the loading bar. Don't think that's significant though. Maybe I should just format.....

Aaagh, oh well, from the Recovery Console issue the commands fixboot and fixmbr as a last resort :)

I've never used these, there could possibly be a switch or something to specify the partition for fixboot

Darn, the only other suggestion I can make is using a boot CD such as Winternals 4.2, Ultimate boot CD, JTech's Boot CD etc
But you're probably right, a format or reinstallation would probably be quicker

Fixboot and Fixmbr are more for errors such as 'Cannot find NTLDR' or a non-bootable hard drive.

My hard drive boots fine, so I guess I will format.

Dammit, formatting after Windows has been installed for 4 hours...

I know exactly how you feel
Just did a quick google & brought up this
http://www.annoyances.org/exec/forum/winxp/1072915768
Some problems were solved & most seem to be BIOS related
May be of some help
I'll certainly be copying them

You could check the ms site out http://www.microsoft.com

Type in 885626 up top in search. Sound like the prob you're having??

This article describes how to resolve an issue where your computer stops responding (hangs) when you restart to complete the installation of Microsoft Windows XP Service Pack 2. This issue occurs on a limited number of systems that use a version of basic input/output system (BIOS) that does not have production support for Intel Pentium 4 and Intel Celeron D processors based on the Prescott C-0 stepping.

This issue may occur if the following conditions are true:

Your computer uses an Intel Pentium 4 or Intel Celeron D processor that is based on Prescott C-0 processor stepping.
Your computer has a BIOS version that is out of specification.

Note A BIOS version that is out of specification does not provide support for the processor that is installed on your computer

Looks like the solution.

Only problem is I have formatted, reinstalled XP and sent the PC away to my customer.

I downloaded the patch, and I will put it up on my customer download site and tell him to download it before installing SP2.

Cheers for all your help.
