A couple days ago my computer which is running windows 7 pro 64 bit started rebooting after it got to the windows logo after turning on the computer then giving the option of using start up repair or starting normally. I clicked the repair option and like the title said it cannot solve the problem. I haven't really tried anything yet so any advice is welcome EXCEPT reinstalling the OS. I have hundreds (literally) of gigs of data on that computer and cannot afford to lose all of it. Also booting in safe mode will not work either.
