Well I'm fixing yet another friend's computer later today but I don't have many ideas on how to fix it. Basically one day when she turned it on and got a black screen saying: "windows did not shut down properly". When she loads the PC up in normal mode XP will load but a blue screen will quickly pop-up and the system will start-up again. I googled and found this page but it's basically telling me "reinstall" which I don't want to do. What other options can I try? I will try doing a repair install in recovery console and see whether it boots into safe mode. Any other suggestions that don't involve reformat?
