Keyboard going haywire!

[WITHTEETH]

So I had windows XP and a Saitek ilumanted Keyboad and I got a BIOS update. Well I Soon after noticed problem with my keyboard. It would start to repeatedly hit keys like 56'56'56'56'56'56'56'56'56'56' over and over. Or will repeatedly hit the key between the shift and the X which i cannot hit because this same very problem! wth is going on with my computer? I even had issues in the BIOS.

this is what i tried in order to correct problem -

had winXP installed win7 64bit still had issue
updated bios, same issue.
Installed chipset drivers, same issue
Installed NEW keyboad same issue
Installed new chipset drivers, same issue.

Any Ideas Im at a loss.

thanks in advance guys. And to just reiterate. Its not my keyboards since I've tried 2, atleast im pretty sure...
