Keyboards Not Functioning When Windows Boots Thank God for Ubuntu


BlueInkAlchemist

Greetings, all. I'm in the process of fixing my PC after a near-catastrophic failure. Things got too hot in my case, shorting the power supply and blowing capacitors on my graphics card. Those parts have been replaced and the PC now boots fine.However, as Windows loads, the keyboards (I have both a PS/2 and a USB keyboard) cease to function. They work just fine up to a point, but during the Windows loading process the lights flash on then off, and no amount of typing or facerolling produces any output. The pair of times I managed to get it booting into Windows' Safe Mode, it seemed to hang up on 'Mup.sys' but I don't know if it's related. I can access the BIOS just fine with the keyboards, and when I pop my Ubuntu disk into the system, it has no problems allowing me to use my keyboards. So, considering I can access my system in this semi-backdoor fashion, is there a particular way I can check the *.sys files of Windows to see if some of them need replaced? I'd like to avoid reinstalling XP if I can. I believe it won't be that large of a hassle given that my partitions seem to be intact, but I don't want to risk losing anything else.

Have you tried booting from a known good operating system? If you do and the keyboard works then you know its a software problem, not a hardware problem and you probably just need a fresh install of windows. Also, I'm not totally sure but doesn't windows have some sort of safe mode where it doesn't load all of it's extensions at boot? If the keyboard works at first but stops working after windows has completely loaded that might be some sort of extension loading that is causing problems

As I mentioned, Mup.sys is where safe mode hangs when I get that option. And the keyboard works fine in Ubuntu. If worse comes to worst I will back up my documents and other things from the system partition and reinstall Windows. Hopefully i can do that without having to repartition my HDD.
