Windows XP Mup.sys hang on startup

Uuggh, my brothers computer is giving me a hard time. When it boots it hangs on Mup.sys. I tried replacing the file, restoring the registry, and renewing a previously working state but none of those worked. I tried several Windows XP disks but they all hang after the "Press F* to install custom RAID drivers" so I can't run chkdsk. I tried going into Ubuntu and running ntfsfix but that did nothing.

I don't know what to do now. The Windows XP disks don't work and I can't get into Windows, I don't know where to go from here.

Edit: SOLVED

    What exactly do you mean by hang? As soon as mup.sys is loaded, all hard drive activity stops, or does it keep accessing yet not go into Windows?

    ...and I thought of how all those people died, and what a good death that is. That nobody can blame you for it, because everyone else died along with you, and it is the fault of none, save those who did the killing.

    It's actually hanging after mup.sys (once it shows a name, that means it's loaded). It's hanging at ACPI init. Try this:

    Change your ACPI settings in BIOS. Reboot, then change them back. Unplug all USB devices except keyboard and mouse, and try booting again

    Hard drive stops at Mup.sys. I'll check the ACPI. It doesn't have any USB devices in, I tried unplugging the CD-ROM drive but that didn't help.

    Edit: Disabled ACPI, didn't work.

    Fixed it, the memory slot had died. Putting the memory in another slot fixed it.
