Windows 7: PC freezes in safe mode on MUP.SYS file

PC freezes in safe mode on MUP.SYS file

I have a PC that froze up during use. No new software has been added, with the exception of Critical updates released over the past month. After a hard reboot, the PC would freeze up during the Windows boot screen - and in safe mode, it freezes while loading MUP.SYS.

here is what I've tried so far, each failing to resolve my issue:

* Clear BIOS by removing CMOS battery
* Performing a CHKDSK of the system drive. - no issues found after running for 1.5 hours
* Moved the one memory module to the other available slot.
* fitted different HDD preloaded with fresh XP SP3 from a working PC

I even tried to do a fresh install, it picks up the disc and starts to download the files then the Windows logon screen appears again and it freezes up again I left it for 2 hours last night and it just sat there!

Is there anyone that has any idea what is going on here?!

Related to mup.sys Multiple UNC Provider driver from Microsoft Corporation.

Run a system file check to verify and repair your system files.

To do this type cmd in search, then right click to run as administrator, then
