Do method 1 before you do method 2!
Method 1: Go to start>Run and type cmd.exe
Type sfc /scannow (note there is space between sfc and scannow)
A progress bar should appear in a window, insert your win xp installation disk and let it restore system files. Once complete, restart computer.
Method 2: Go here to repair all system files without removing your personal files or settings/favourites/documents/pictures...etc: http://www.michaelst...pairinstall.htm
Hope this helps!
I tried method 1 but that didn't work. Now, I don't want to try method 2 before I can backup any of my files, but how would I go about doing that?? I've never made a backup disk or anything before.
