Windows7 will not boot. blue screen!


New Member
I have a dual boot system win7 and xp. I started getting a blue screen about a week ago when I try to boot win7.
I ordered a new disk but hesitant to use it for fear of losing all of my data.
I can still boot to xp but I can't access my backup hard drive. My system is as follows:
Dual Boot win7 & xp
Asus M4N78 pro motherboard
AMD Pienom X4, 9850 processor
NIVIDA 9500 GT video card
