Vista PC Black Screen of death.

My PC froze and shutdown on its own. Upon restart, it got to the part where the green bar moves across and says MICROSOFT, on a black screen background, but never goes any further. I can (and am doing this) in safe mode with networking. This issue has occured before, but the pc usually just starts normally if i reboot enough times. And it wont happen again for many months. This time, many reboots has not fixed the problem.


Please note, that the eventviewer has around 6000 entries in it since 2009, and these from this recent reboot.
