A friend of mine has a dell 2300. Everytime you start the computer it gets to the windows xp loading page and I get the blue screen saying registry error. I tried re-installing xp but when it loads all the files and asks me if i want to repair windows or install new copy I get the same blue screen. I reset cmos with no luck. I can't think of anything else to do since I can't even reformat the hdd. Any ideas?
