Maybe if you did a reformat that would help. Call the maker and they can walk you through it, I had to do one and it takes the computer back to the day you bought it, you will lose everything but it really works. Hope that helped.
The expert said it would be useless, because this puter (which I didn’t get new - it was someone else’s work computer long before it was mine) just doesn’t have enough oomph or memory to support all the needed firewalls and defense stuff required by XP in today’s spyware and virus environment.
Thanks for the suggestion - I asked about doing it, but that’s the answer I got! Since I have the other newer computer, but it isn’t compatible with my very old monitor, I just need to get a new monitor - but no money for it or way to get one.
