Hello Corrine.
Thank you for your response. Sorry for the delay in replying,I have had some problems. Your solution did not work. I reloaded XP again and discovered that it can be loaded only for a specific number of times, which I appear to have exceeded, and then the key does not.work. I can't load any updates. My son has a computer tech friend who builds specialist computers and networks professionally. He said my machine is not worth repairing even if I bought all the bits and did it myself as it is 5 years old. A copy of XP SP3, reputedtly genuine, is nearly half the price of W 7. He recommended Compaq and I can get a base unit with Athlon processor, 500 gb hd, 4gb memory, W 7 Home Premium, etc, new, for 1-1/3 the cost of repair. I don't play games and don't have much correspodence. My son will make a big contrbution for my birthday so that is what I am going to do. Will programs that I have downloaded and which can be trsferred to DVD work with W7?
Regards.
