I have tried multiple keyboards, both wired and wireless in all USB ports (no PS2 ports) and none of them work at all once Vista (32-bit) has started. Even the Num Lock and Caps Lock keys don't change the indicators on the keyboard itself once Vista starts, including Safe Mode. Keyboards work fine in BIOS, and when I booted with FalconFour's "mini-XP" OS it worked fine as well. Also, there are no problems with the mouse. I can do everything normally using the on-screen keyboard. I've run Glary, ADWcleaner, registry fix with CCleaner. Removed any suspicious programs. Tried uninstalling the HIDs and using "scan for hardware changes" to re-install them. Nothing has had any effect.
It is a friend's PC and she REALLY wants to avoid a System Recovery but it's looking to me like that will be the only way to get her keyboard to work again.
Any help would be greatly appreciated.
