XP Booting issue - mup.sys

Microsoft Windows xp home edition
January 9, 2010 at 09:14:51
Specs: Windows XP
OK, have 2 bootable drives in the computer. All was well. All of a sudden when I boot the computer it shuts down during the Windows loading screen.
Have checked the CPU temp never above 40C. Havent installed any new hardware. Memery (4Gig) is fine.
Now, originally this happened on the first drive (Lets call it A) When this first started happening turning the computer back on got me to the "safemode" screen and I went to it. The computer started in safe mode upon rebooting the boot was fine. At the same time the second drive (B) was fine. Booted normally.
But after rebooting after the first safe mode was successfull again the computer turned off again at the Windows load. Now when I try to boot in safe mode it hangs at mup.sys.
Now that drive isnt bootable at all.
I said that the second drive was fine but now I have had the second drive shut down the computer at the Windows load.
OK, I put the Windows disk in and did a recovery scandisk, found and fixed some errors but did still sut down the comp. Then I repaired the "A" disk windows installation. Nothing, still shuts down at the windows load.
The point I am at right now is the A is unbootable, but accessable through the second drive (When the second drive decides to let me boot through it), (I am on the drive as we speak).
Why is the comp turning off. I know that there may be somethings that i have left out that I have checked but all seems well, just wont boot. :(

Did, other than a new installation of windows were no real helps there. My concern really isnt the Mup, but why now it is both drives that shut it down. and why randomly I can boot the second drive.

If you installed the OS on the second drive when using Windows on the first drive then the ability of the second drive to boot is dependent on the first drive.

Why didn't you provide more information on what OSes are installed on each hard drive. Also, folks confuse partitions with hard drives. Are you using 1 or 2 hard drives?

OK, like I said I knew that there would be stuff that I didnt include that may help :(
2 Separate hard drives
Drive B ( Drive B now but was originally drive A) Installed originally. Loaded with Windows XP Home Edition SP3. Originally only drive in the system (160 gig)
Put second Hard drive into the system ( Drive A ) for the Windows 7 Beta. Was set up with 7 beta till it got too buggy and I wiped it. Installed XP Home Edition SP3.
Both hard drives installed with XP Home SP3 and ran perfect.
This the point where I switched them from A to B and B to A why? I made the second drive A because there was more room on it and the first had some programs on it that I didnt want to put on A. Basically A Just became my "go to" drive for basic comp operation. No giant progs.
OK Even after the switch they ran perfect always did, until recently. For no apparent reason things started as per my original post.
Just in case I wasnt clear they both have bootable separate installations of XP Home SP3. So both are bootable after POST, I choose as per what I am doing at that moment. :)

How did you "switch" the drives? Most modern systems allow you to select which drive to boot to without any physical reconnection. If you select drive A for instance then next time drive A will be the default drive. You can still go to the selection menu at start up and choose a different drive.

Did you install the second instance of WinXP while the other hard drive was connected? If so, then they are still joined at the hip.

Why do you want two instances anyway?

Your do realize that you can install or save anything to any partition/drive in your system. No need to swap drives because one has more room.

OK I dont remember why the drives got switched, I was having a problem with something at the time and I think I just mixed them when I put them back in.
I know about the selection because that is what I do for the boot that I want to load.
I did install the second load of xp while the other drive was loaded. Are they joined??? I dont think that they are. There were hardware changes that I made that werent on the opposing drive ( I was using the one drive most of the time at this point so I wasnt needing the other drive for anything.) Not to mention I had to go to SP2 on the second drive long after I did it on the other drive.
If they are tied together how? I was curious about that upon doing the second installation, but things along the way that I noticed led me to believe that they arent.
Anyway... I dont need to instances, just had things on the one that I dint want to moved and programs on the one that I didnt want to reinstall. Not to mention, I was a little concerned about the original drive being lets just say... a little infected or corrupt. I have been meaning to reformat everything just to get a clean slate ( I usually do it every 6 months) but I have been slacking as of late.
The reason for my posting really is that i want to make sure that I dont have a hardware problem before I reformat. If it is just a sofware prob them a reformatting will be the solution and all will be well in the world.
Kinda funny, drive wont boot ( hardware? Softare?) then it does...(Hardware? Software?) If it was hardware then it would never boot. If it was software then it would never boot I dont know LOL Just a real Pain in the butt!!
and yes..... I do know about partitions, saving and accessing across them. Just a victim of circumstance in the making of the seperates.

If you are concerned about the hard drives then run a drive fitness test on each of them. Get that utility from the manufacturer of the hard drive.

OK heres the scoop. Not good unfortunately.
Dumped the drive. Repartitioned and formatted. Installing windows all good until it installs devices. Then it turns off. :( Well at least now I know that it is a piece of hardware that is doing it.
Is there any way to find out which? I know that the last piece of hardware that I have installed was a new vid card. That was like 5 months ago. Its an Nvidia 9600 PCE. Any ideas. :(
Also... solo drive now, I pulled the other one out.

What service pack is integrated into your WinXP CD?

Disconnect all external hardware like printers, cameras, card readers, scanners, etc. Use a PS/2 keyboard and wired mouse to install.

Graphic card shouldn't be a problem.

Unplug the other hard drive. You could also disable integrated hardware until after you are up and running with updates, etc.

Do you have a SATA hard drive?

Then you must supply SATA controller drivers at the start of the installation. OR, if your BIOS supports it you can change settings for the drive that doesn't require that you provide SATA drivers.

I assume you don't have a floppy drive?

Either set to AHCI or to run in an IDE compatibility mode. This is probably why you had trouble after swapping the cables around. The BIOS may have automatically reset to SATA mode.

AHCI is fine to use if available. The best solution is to provide the SATA drivers.

You could slipstream them into the files on your WinXP CD. You can also put in SP3 and other stuff.

Slip streaming is a process promoted by Microsoft to make installing easier. There are 3rd party programs that make slip streaming easy. nLite OS is what I have used.

Well then, if you finished the install and the computer booted to Windows it must already be set to one of the above settings in the BIOS.

Let it set for a few then boot directly to the BIOS screens and look for PC Health or similar to check the system temps.

Set in the BIOS for at least 5 or 10 minutes. If the computer doesn't shut down then boot into safe mode and see what happens there. While in the BIOS check to see the voltages and RAM settings.

One thing you can try to do is to re-seat all cables, cards and RAM. Snap each RAM stick in & out 4 or 5 times to scuff up the contacts.

The screen that you got the other voltages from doesn't say anything about 12V?

What is the heading of that screen?

Without any 12V power your computer would not be running.

You don't even need SP1. SP3 is a rollup of everything from day one. Of course you need SP1 to use large drives and there are plenty of updates since SP3 probably over 100 by now. Was 82 a year ago.

OK Interesting turn of events. Have no floppy (memtest needed a floppy for boot) Did have a USB external floppy, I plugged it into the usb port. Instantly comp shut off. Tried restart and was shutting off at the original windows load like before. Removed it and Windows boots all the way no prob. It will shut off eventually though, but do you think there is a USB prob. They keyboard that I have on it right now is USB also. Im going to look for a normal one and see if the system shuts down.

You don't install memtest86. Get an iso, burn it to CDR and boot to it.

No details goes right to CMOS Set up Utility with the PS2's connected. Save or Dont save and exit......right back to it when restarts.

Also burned the iso to a dvd, but wont boot to it. Shows "Boot from CD" but then loads windows.

Googling produces lots of hits.

http://www.google.com/search?q=+MBR...

Also, get memtest+ to run from the boot. There are ISO files for download. I don't knwo why they wouldn't run if you made the disk right.
Can't recall if you ran fitness tests on you hard drives. If not I suggest you do. Get them from the manufacturer's site.

For what's it is worth: I was hit with the mup.sys freeze right after using media player. My browser (IE8) began directing web pages to a variety of marketing web pages. I have XP, and service pack 3, as well as paid editions of Superantispyware and Malware bytes. I ran scans and found several pieces of malware and trojans. The scan picked them all up. I tried to go into safe mode to run another set of scans and that is when the mup.sys freezes began. Although my browser "worked" it would still occasionally fix to other ad pages. Scanned again with SAPW and MB and both came up clean. Tried Combofix and it showed nothing.

I read all the boards I could find and disabled all external drives, usb and everything else. The safe mode boot still stalled at mup.sys. I even let the laptop "sit" on the safe mode screen for 3 1/2 hours in the hopes that time might at least get me into safe mode so I could scan whatever was still there. The screen did not budge.

In desperation, more than anything else, I loaded up Microsoft Security Essentials and scanned the computer. It found 5 trojans that are relatively new (all listed as late 2009 or 2010). It removed all five. I rebooted and safe mode popped right up. The computer is back to regular speed and works like its charming self.

This may not work for everyone, but give Security Essentials a try (it's free on microsoft support). Thanks
