When booting, before you see the windows loading icon press F8. Select Last known config that worked to see it that fixes it.

Usually this happens when the vista boot loader fails. During boot up, keep tapping F8 and then select Disable Automatic Restart... and get the stop error code which usually starts with 0x

This sounds like the dreaded Windows Vista Black Screen of Death (KSOD). you might have a bad hard drive, but even more likely some software or a driver is causing a problem and caused Vista to get stuck. The repair will not work. You might be able to run a complete repair from the Windows Vista CD, if you have one. If you are not too experienced, take it to a reputable computer service center. If you are at all technical and have time, google your problem and you will see thousands of similar users with same problems.

This is one reason Microsoft released Windows 7 so soon.

Hello,
It sounds to me like the harddrive has errors on it. First, I would try completely reinstalling windows with the windows disk. If that does not solve the problem there are several pieces of software that are much stronger harddrive repair solutions than the built in Windows one. Try this one, it is free for 10 days. You will need another computer (friend's computer?) to download and burn this software onto a CD, then put the CD in your computer and boot to it by pressing any key when it asks you to.
