Keyboard ( on boot )

Hi

I got a IBM - Thinkcentre
With Windows Xp on.

Here is the deal
When i start my PC it goes normaly thru the "Press Enter to setup BIOS" .
Then it moves to "Press F11 to start system restore" ( IBM's Restore partition )
In this case i need system restore Due to settings made that cannot be reversed by "Windows System Restore" manager.

The problem is. when i press the F11 or not my Keyboards lights start flashing in this sequence:
Numlock on
Numlock off
Capslock on
Capslock off
Scrolllock on
Scrollock off
and keeps cycling till Windows Boot screen.
When i try to press something it doest react, in this case to set the restore options on IBM's Restore Partition

i feel like wanna :angst: :angst: :angst: :angst: the machine. but i decide to :surrender: :surrender: and look for some professional help ( Microsoft site is a ripoff )
:help: :help: :help: :help: :help: :help: :help: :help: :help:

No one can help ?
