Need help with my computer. I have 120gig and 40gig drive. i havnt touch my computer but what ive done is sent all my stuff from my 40 gig drive to my 120gig drive (just music and information) and i defraged my 40gig drive. but now when i turn on my computer everything fine it loads to the black background with windows xp then it goes black and nothing works. when i try to do a safe boot it stops at

multi(0)disk(0)rdisk(0)partition(1)\windows\system32\drivers\Mup.sys

anyone help?

google says

Hi my XP Pro system got the mup.sys error just out of the blue today. Here's what I did:
1. Ran XP setup and logged onto my C:\windows
2. EXPANDed the d:\i386\mup.sy_ file to C:\windows\system32\drivers folder

after a failed reboot or two I then followed the advice of whoever wrote about pulling out their mouse lead during safe mode boot.
I was running a Logitech cordless mouse off that system at the time and I did the following to get XP to boot successfully:

1. made sure ACPI, Plug & Play, USB all enabled in BIOS

2. moved mouse from the ps/2 port to the first USB port
3. booted using safe mode
4. waited until it hung at Mup.sys
5. removed the mouse cable from the USB port
6. (3 seconds or so pass, the screen went black and safe mode appeared)
7. restarted system
8. booted normally into XP Pro

that didnt work but what ihave worked out is in safe mode and it loads that mup file i press esc quickly and it goes into safe mode

go to do a repair and do a chkdsk /r ... see how you go.

Providing you havent disabled system restore points, have you tried selecting "last known good config" on the OS boot menu?

F8 will bring that up before windows loads, just sit there tapping it and if a device boot menu appears (CD/floppy/HDD) just select whatever and immediately resume tapping F8 to bring up the OS menu.

From your last post it looks like you are saying you can get into safe mode, if so try rolling back to a diff restore point.

i was reading forums and they believe its a bios or maybe usb or maybe a hard drive cable problem..... i have disabled system restore as i havnt installed or download anything for about 3 weeks
