My daughters computer (old Gateway-running Win98)froze up,when rebooted,msgsrv32 message pops up, then the illegal operation box comes up. A Go Back (restoration program) was run now NOTHING comes up on the desktop, the "Close program" box on a ctrl-alt-delete is empty (???) If I try to restore the C drive, will anything come back or do I have to re-install Windows......how do I know how much of the current Windows is left? It looks like.....NONE? Can I just re-install from WIndows disk?
