2 days ago i updated my dell xps windows vista. and now when i try to turn it on it freezes at the windows loading screen. i have tried the auto repair thing it tells me it cannot fix the problem. i donot have any restore points. and have alot of important files i dont want to loose from wiping it clean. is there anything i can do? also i have sent reports of my problem after the repair tool finished. but i dont kno what that would do since i cant get onto my comp anyway. thanks for the help!
