Did you just install the .net framework? This is an issue that I've had in the past.
Try turning off the machine, and remove a stick of RAM.
This should allow you to boot up normally. Once you get in, shut down and reinstall the stick.
Then I would confirm that you are running the latest .net framework build.

MUP.sys just happens to be the last file that gets loaded during boot (as you will see if you boot a healthy system to Safe Mode).
So all you can say is that *something* is going wrong in the initialisation period after that. One distinct possibility is a video driver problem (it will be *some* driver), so I suggest booting into Safe Mode and running MSConfig.exe. In its BOOT.INI page check /BASEVIDEO and reboot to normal mode. If that comes up OK, look for
updated video drivers from the maker's site (do *not* use ones from Windows Update)

Try running ChkDsk from the Recovery Console.

If they don't work you could try repairing windows itself by running it over itself. You will lose all your windows updates but your files will be untouched.
