Hi, guys. my daughter's keyboard and mouse stopped working on her PC.(ps2).I thought PS2 might have become disabled in the bios, so i removed the mobo battery to clear cmos, hoping to restore defaults and enable ps2 function. now, on booting i get a message along the lines of ".....defaults have been reset. press F1 to continue, or Del to enter setup". However, the keyboard still doesn' work. i can get no further. Is it all a lost cause now? Kb & mouse are both ok, work fine on another PC.
