OK this looks like it cant be fixed,i was given a PC by a friend when turned on a few thing appear like no 0 drive found,when i try to run an xp install it starts loading file then turns to the blue screen of death this keeps happening,when i try a vista install i get as far as what drive do u want to store it in but i don't see any drives the box is empty,i think someone might have deleted every thing on the PC. a A message did appear saying something about contact symantec,so i think it was fried by one of there data delation softwear disc's. Thanks PADDY
