I searched the Internet what to do about the problem on the subject, and one forum said that this is caused by removing viruses with McAfee anti-virus (which I did). They suggested to fix that through msconfig but the msconfig doesn't open. I went to a forum that gave solutions for downloading msconfig but they don't work. I started XP in the save mode and Run but still no msconfig. Another forum said to download an alternative msconfig which sits on the control board, but that also didn't work. I tried the suggestion to type in Run sfc /scannow and insert the XP disk but also no result. Anyone more suggestions?
