Mouse and keyboard not working

[Guest]

Situation: a friend's XP Home stopped booting--even in safe mode--after
doing latest updates from MS Update. (BSOD c0000269 - illegal relocation of
DLL) Got that fixed by running a batch spuninstl of SP2 from the recovery
console. Now it will boot to the login screen, but neither the mouse nor the
keyboard is working at all. Both are PS/2. Have tried both safe mode and
normal boot, as well as two different mice and two different keyboards.
(Only one of the mice is optical, btw.) Mouse and keyboard work fine in the
BIOS and to run the recovery console from the CD, but neither will work
inside Windows. I'd appreciate any suggestions!

You most likely have a corrupted registry.

Go to http://support.microsoft.com/default.aspx?scid=kb;en-us;307545

The solution is long and tedious but it will rescue your computer. I have
done it myself. I had exactly the same problem when I deleted the wrong keys
from my registry accidently and I was able to rescue my computer.

Good luck

Thanks, James. I started the process described in the article, but in "part
two" I am unable to boot to safe mode. The file list stops at
\WINDOWS\System32\Drivers\Mup.sys every time. Suggestions for continuing? I
really appreciate your help.

I am very sorry that I have no simple answer. I goggled 'Mup.sys' and found
many people with the problem and few answers. Here is a link to one post I
found where the guy seemed to have solved the problem.
