This could be a malware issue, a problem with Windows, your video drivers, an issue with your hard drive, or a host of other things.
Can you connect to the internet to do a malware scan? If so, try this free one: http://housecall.trendmicro.com
If not, do you have a copy of the Vista installation DVD, or can you run "Repair your computer" from the screen that launches Safe Mode?
To get to the Safe Mode screen, start tapping the F8 key before the Windows splash screen appears. For more instructions on Startup Repair, visit this link: http://www.bleepingcomputer.com/tutorials/repair-windows-with-windows-startup-repair/
If you can get into Safe Mode, try uninstalling your video drivers. Let us know the make and model of your system so we can look up the replacement drivers that you'll need.
