PS/2 keyboard not works in BIOS but not in Windows 7

[Siddharth_1]

I have a ps/2 keyboard. I recently upgraded to windows 7 64 bit, but my keyboard stopped working. It works fine in BIOS. It worked fine in windows 7 32 bit.

MAINBOARD - MSI Z68MA ED55 (B3)

'not works in BIOS but not in Windows 7' sounds more like a typo to me.

If its not working with your pc, try to attach it at some other pc to see whether it is working or not, or you can even try other keyboards in that ps/2 module.
If the problem continues then go to service center with your mobo.

There is no problem with the motherboard. The keyboard is OK as it works properly in BIOS as well as Windows 7 32 bit, on the same motherboard. The problem is with Windows 7 64 bit.

Also the NUMLOCK, SCROLLOCK, CAPSLOCK and OFFICELOCK buttons, when pressed nothing happens in the OS but the LEDs in the keyboard respond. This proves that the keyboard and the mobo are OK and the problem is with OS.
