I have a huge problem and I can't fix it. I've looked all over various boards, and done all I can think of. I ran spybot -search and destroy (it was updated), it found 3-4 entries, I researched each one to make sure they're all spyware. Then I deleted them and rebooted. Keyboard stops working. went back to spybot, restored the changes it had made. Same problem. the keyboard doesn't work in safe mode, but it does in BIOS. The NUMlock led is on during regular windows sessions, but none of the leds can be toggled. the mouse is fine, the usb ports work fine. the keyboard is ps/2 but I also have a usb adapter, neither works. It's drivers are kbdclass.sys and i8042.sys kbdclass.sys can be deleted/reinstalled however I want. But i8042.sys cannot. If I remove i8042, unplug the keyboard, and reboot, no driver installed. plug the keyboard in (usb OR ps/2) it finds i8042.sys right away. I can't remove this driver, even if I go to system32/drivers and delete it, as soon as I press F5, i8042.sys is back (this might not be bad, I don't know). The keyboard is generic. Windows seems to switch off between giving me a code 10 and a code 13 when I go to device manager. (there is always an exclamation point by the keyboard these days) I saw online some people had a similiar problem and fixed it by going to HKEY_LOCAL/system/class/random_number and deleting the Upper_filter and Lower_Filter registry entries. didn't help, put them back. Nothing else seems to be affected. I went into BIOS and toggled all the I/O variables (when I get this desperate I just start randomly clicking things) one by one. Each reboot was the same. If anyone has any ideas please help.

Probably far too simple (as nobody has answered): 1. Have you tried another keyboard? 2. Have you tried deleting the Device Manager entry and rebooting? DerekW

yes and yes

No surprise. Post seems to have foxed everyone. DerekW
