I'm having a bit of a mare. A couple of weeks back i ran system file checker and long story short I ended up with an unbootable instal. A mate tried to help but was unable so put windows 7 alongside my old xp. Not getting on well with W7, my motherboard doesn't support it apparently and grahics drivers continually crash/ stop responding. Q. Can i get away with reinstalling XP over the existing corupt copy - i really wish to keep installed programs and access to files etc. Is there an easy route for me to take that doesn't involve formating?
