think my original post was in the wrong forum, so i'm reposting it here. My son was using my comp. 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.He'd been able to continue working on my comp even with this green screen. 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. When I try to reboot it in any of the modes it appears like it's going to reboot, a blue screen with flashing numbers appears for a 16th of a second and it comes back to the start up screen. 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 is my dream comp with so many programs that I've always wanted..Can I use the recovery disc from my former PC? I've located instructions with how to get everything going again so I think I know what to do-but just afraid to use a dif. comps recovery disc. Of course if someone here has detailed directions on how to restart it, I'd appreciate it- I don't know if the instructions I've copied are correct. HELP!
