Vista - Computer Boots but Vista wont Start

No indication of any problems before this happened. No new hardware added.

I shutdown Vista for the night and it stayed on "system shutting down" screen so I manually shut it down.

Now when I try to start it the computer goes through the normal boot and goes to the first Microsoft screen but stays there for awhile and then goes blank. I have tried to get it going numerous times but same results. Tried last know good configuration one time but didnt work.

Anyone have any ideas other than clean reinstall that I can try?

This is VIsta 64

The manual shutdown is not good unless you have your power switch setup in your BIOS to wait 4 seconds while it does some things.

Sometimes there is a long display of the black screen after the windows scrolling green dashes screen. You may should have waited but if it takes more than 10 minutes.....oh well.

This simple thing has brought me back before after a power failure made my reboot do as you are describing.

Disconnect all peripherals. All you want connected is the main hard drive, display, mouse and keyboard. No thumb drives, external drives, nada, zilch. Then attempt a boot.

The next day it started fine and havent had a problem since so I dont know what happened.
