hi people. got a problem with my pc again. all of a sudden, without any warning, my keyboard stopped working. it was a wireless so i thought the battery died but putting new batteries didnt help. i even brought a new keyboard today, but still no result. not getting any error messeges or anything, pc starts up normal. just no keyboard. using the on-screen keyboard which is annoying. tried using ps2 port and the usb, same again. all help is appreciated. thank u.
