My son was using my comp and when he got the message that I was infected and had to run IS 2010 he had no idea that it was a virus. By the time I got home my comp had a green screen saying I was infected. I shut everything down but when I turned it back on. NADA. I can turn it on but it won't start in any mode. Not safe, not last known config.etc. This comp was custom built and the company is now out of business.I was never given a recovery disc for it. I have a recovery disc from my last comp which also had Windows XP. I don't want to lose any of my programs. This one is my dream comp with so many programs I've always wanted..Can I use the recovery disc from my former PC? I've located instructions in how to get everything going again so I think I know what to do-but just afraid to use a dif. comps recovery disc. HELP!
