Keyboard stop work on xp installation

Hi,
Any help would be great.. I have just started a fresh copy of widows xp and during the installation setup my keyboard has stopped working... Got through entering the key but with 33 minutes remaining and stuck at the screen ( personalize your software ) thing have gone bad..I have no keyboard function and can only use a mouse when plugged in... Oh forgot to say its a Acer Aspire 3000 laptop.. Thanks in Advance
