Okay here's the problem. About a year ago, I built a system for someone at work. It's an XP 1700+ with a Biostar M7VIQ motherboard, 256 megs of PC2100 Crutial Ram and Windows XP Home. About a month ago, I got a call from her saying her kid was using the computer and now she gets errors when starting windows. I took a look at it and figured the OS was hosed so I pulled out my USB hard drive and dumped the ghost image I made of the computer before I gave it to her. Same Problem.... Windows boots up with a black screen and just sits there. If I choose to boot into safe mode, it'll scroll down all the driver components its loading, then just hang at mup.sys or If I choose to boot windows normally, it'll go back to that black screen. I replaced the RAM and it still did the same thing, so I did some more tests and nothing changed. Then I installed Windows 98 from one of my old cd's and 98 worked fine. Then I tried to install Windows 2000, and that works fine as well.. Then I tried XP Home.... it goes through all the drivers loading, but then it hangs when it gets to "Setup is starting windows" and does nothing else. I thought it might be a problem with the CD, so I took my own copy of XP Professional and it did the exact same thing.


At this point, I was overly frustrated and figured it might be a problem with the motherboard, so I RMAed it back to Newegg and they sent me basically the same board, but another brand back. I just got it the other day and when trying to load the computer, I get the exact same problems again.

Does anyone have any clue wtf is going on? I guess I could load Windows 2000 on the system, but she paid for a Windows XP Home license and would probably be pissed that 2000 is now running on her system. I can't think of anything else to do here. I've replaced everything but the processor, but my guess is that if it was a processor problem, the computer wouldn't even boot correctly, let alone run 98 and 2000 stable.

Any ideas? I'm dying here..
 
there's a thread on annoyances.org about the mup.sys hanging.

i had a problem with that file several months ago too, but unfortunately i can't remember what the hell i did to fix it!

hope that link helps...
 
Well I just replaced the HDD and that didn't solve it... i SO do not want to rip out my own CPU and put it in this thing just to test it.... argh....
 
i had the problem with my sisters computer. cant remember what i did to fix it... start by resetting the bios and boot from teh default config. i belive that error normally has something to do with usb configurations and usb devices. keep us informed on what you find bro.... may the force be with you.

Thanks for the encouragement :) If you happen to remember what ya did to fix it, let me know. Hopefully this thing won't end up in pieces by the end of the week.. The only thing I can think of is it's the processor. Let's see if newegg will replace it...
 
Um, didn't he just say it might have something to do with the USB configurations? I don't think it's the CPU.
 
Hold on, DON'T replace the processor. It seems WinXP is reading some code off it and this needs to be disabled:

(check back here for some copy/paste stuff)....when I say I'm done, that will be it, here's something to get you started (don't try any of these until you read them all):

SECOND
"I had this same problem. it actually caused me to buy a new processor that I wanted anyway, but I couldn't get the computer to boot off of the WinXP Pro CD. It would always hang at the file that supported multiple processors. I finally fixed the problem by disabling the quick POST in my BIOS. for whatever reason, this solved the problem. maybe that will work for you without disabling the DLL in windows."

THIRD
"I think mup.sys is getting a bad rap in all of this. I had the problem, where booting in safe mode, the computer would hang, and the last line listed was the mup.sys line. My problem was actually solved by moving a ram chip from one slot to the next adjacent slot. The computer will hang if it gets a bad read from a ram chip, and in this instance, it was hanging coincidentally when the mup.sys line was displayed."

FOURTH (no, not the cats, hehe)
"Agreed. I was able to get into the recovery console and successfully disabled mup. (For the record, you just type disable mup, not disable mup.sys.) After doing this, I rebooted in safe mode and now it just hangs in a different spot. I'll keep working on mine and see if I come up with anything. My theory is that my cats knocked something loose and now bootup is hanging. Stupid cats."

FIFTH
"I just ran thru the same problem. But mine's worse. When i try to boot up using the win2k setup CDROM it would also hang. Finally i managed to get Windows to startup by removing all my PCI cards, moving my boot drive from my IDE controller to the on board IDE controller, and moving one of my 256 DDR RAM to the next slot. I removed all the hardware listings (under hidden) and reinstalled each PCI one by one. Now it works. Thanks guys for your posts to help me get started. I have been so stressed out and irritated by this MUP.SYS issue."

SIXTH
"Boot into safe mode with command prompt. Get a copy of mup.sys off of another XP machine. Put it onto a floppy and copy into c:\windows\system32\drivers This will take care of it in 5 minutes or less."

SEVENTH
"I had this same problem in Windows XP and finally figured out what fixed it in my case. I couldn't boot regularly, safe mode, from the XP CD, etc. I had no way of getting into the system! The USB problems people have mentioned on various message boards prompted me to check my usb mouse out. It's an optical mouse so I could try it in another machine and tell immediately whether it was working (since it lit up). Unplugging it and plugging it in again while the machine was off didn't help. But when I got to the mup.sys line while safe mode was booting I unplugged the USB mouse and the machine continued to boot! I now have the mouse plugged in and it reboots with no problems. So, yet one more thing to try; unplug all of your USB devices after the mup.sys line appears. It may just continue!"

EIGHTH
"I tried disabling the mup and it just hung at a later point, so I unplugged all usb devices and chose last known good configuration. This finally got me into windows xp. The first thing I did was go to System restore and go back to the last system checkpoint. After the system restored successfully, I plugged everything back in and it seems to work fine. I think it had a lot more to do with choosing last known good configuration as I had not chosen that before."

NINTH
"I recently had the experience of Win XP hanging during load, with nil on screen, and eventually figured out it was stalling at mup.sys. Tried rebuilding the PC but the Win XP install wouldn't run. Then booted from floppy & re-formatted HDD, still no joy. It was then that I realised that earlier that day I had gone into the ROM BIOS and enabled the Bios antivirus facility. So I disabled it again. Having now rebuilt my PC without incident, I tested this again by re-enabling the BIOS antivirus, and sure enough the PC wouldn't boot. This may not solve anyone else's problem with mup.sys, but thought I'd share it just in case."

TENTH
"My son's computer hung at XP mup.sys as well. Just prior to re-formatting the drive and reloading we noticed comments here re usb and tried unplugging the new USB hard drive storage device. XP then started without a hitch. It seems to be a USB problem and an intermittent one at that. The drive is a 2.0 USB but the computer is 1.1."

ELEVENTH
"Restored default BIOS, rebooted and everything worked."

TWELFTH
"OK, I've had the same problem with XP freeze and Safe Mode stall at Mups.sys. Final solution was to re-flash the BIOS (downloaded the file from another computer). It seems to me that Mups.sys is just the last file shown before XP goes graphic mode. It did the same pause once I resolved the problem. It may be at this point that it does the hardware "head count" to match its security settings aginst the activation code. Reading through other forums, it appears that XP is highly sensitive to hardware instability. In my case, the capacitors on the m/board are swollen which may have lead to damaged ROM. Apparently, some m/boards reset the BIOS ROM on ESCD; so occasionally a hardware change fixes the problem and sometimes it doesn't (like my Epox). It became obvious that it was a hardware glitch when Win98 on my second hard drive started to freeze as well. Because of previous fiddling (made the mistake of deleting "viaagp.sys", so lost graphics) I had to do a complete re-install of XP on the main HD; and now she hums along better than before. Next freeze and the M/board gets ditched - it's about 3 or 4 years old."

OK, THAT'S IT! Hopefully, one of these will work. I would try the simplest first though after reading them all. These are the best solutions I could find at that annoyances.org link above. Good Luck!
 
Well fuck me. it WAS the processor. After calming down and playing some AA to blow off steam, i remembered that my fiance has an XP1700+.... i think i already knew this, but i was just so frustrated, i didnt bother remembering.. I pulled hers out and put it back in, and BAM.. works fine. I put the "bad" one in her machine, and it does the exact same thing. I'm so glad I spent the extra $5 and got the newegg extended warranty.... wow. Thanks guys for all your help..

I always thought if there was a problem with the processor, the computer wouldn't even POST..

Ive seen some processors with dead l2 cache that would run like a charm when it was disabled. Or ones that throw out random errors making you think all kinds of stuff.

seen that too. wild when it happens and you see whats causing the problems... dont try to play games on one of those processors!
 
Well, at least I learned a little about the mup.sys problem for my XP system next month. Glad you fixed your problem! ;)
