Well, my old(very old) compaq, has this error when it boots up, yes the keyboard is in the right PS2 port. But i think the problem is with the keyboard, i grabbed a newer keyboard, and it wokred fine, no problems at all. WHat can i do, is there a way to tell what wire is messed? or way to put a new wire in? id apreciate any help at all. the prongs all appear to be fine.
