My XP is corrupted - maybe by an update. I have XP service Pack 2 disc. When I try to reload, I'm advised that I have a later version on my computer so autorun/install won't work - probably SP3 updated later. What kind of problem do I have if I reboot from my disc to recover XP. My problems include: Desk top items will not open on double click/my backup program will not start on open windows/I keep getting an error message when I try to copy from something on the internet and paste into Microsoft Word - says copy created by "package" and can't interpret. Any help will be greatly appreciated. Thanks IA.
