It sounds like a corrupted video driver. Until Vista starts the
video is in VGA mode. The high resolution driver starts
just before the round logo appears. I don't think the video
driver is saved in restore points, so there will be nothing
to restore. Also, in Vista, safe mode does use a high res
video driver, which could be causing the reboot.
If you can get that far, uninstall the video driver, reboot,
then reinstall the latest driver from your card manufacturer,
or ATI, but not from Windows update. It's good practice
to never update hardware drivers from Windows update.
