brother asked me to look at his pc and i cant open anything. tried to start at CMD and cant even get started to look at his system. His norton apperantly was turned off by 'outside' source. Does this sound like only solution is to wipe HD and re-install OS ? If so, how hard is it to wipe. Has a mass produced HPpavilion 523n.( i know, i told him to chuck it :lol: )
