Keyboard driver fail to load, code 39

Hi guys,

I need help..
I've been using winxp sp2 for about 4 years now, I rarely use my desktop pc so after about 2 months since the last use, I started it just now.
The keyboard is not working, I checked the device manager and the property says, the driver fail to load, missing or corrupted.
- Uninstall and install didn't work
- in Safe mode it didn't work
- replacing keyboard didn't work
- restore didn't work
the keyboard only work in bios (at least that means it is not broken).
If I remember correctly, I had Avira and Advance Care System software being the latest installed, could it be related to this?
I have removed them but to no avail.

I'm a novice user, anybody can help? If there has been a post somewhere regarding similar problem, kindly point me to the right direction.
appreciate it, thanks!
