BSOD - No Video output

[Funship]

Problems with Windows 7 Update and ATI Radeon HD 5670 Driver Updates.

A Windows 7 Update wouldn't download (don't have the update # since there is no video output - I'm on another computer). It was 135 KB and "Bear" (on this forum) posted that he wasn't downloading it because of troubles it caused with playig video files.

The answer on the forum was to update the graphics card drivers, so I went to ATI's website and there were 3-4 updates dated 7/26/10. I downloaded one of them and rebooted the computer. When it restarted, IE froze trying to regsiter the update on an ATI website.

After that, the screen went black. I kill-switched it and restarted it. The BIOS screen appeared and the Windows logo as well, then I never got the Windows 7 Welcome screen; instead the screen went black. It repeated.

I started the computer in Safe Mode and rolled back the driver for the Graphics card. I restarted and the screen went black. I restarted in Safe Mode and all the desktop icons were gone - I got a black screen with only the words "Safe Mode" visible.

HELP! What should I do?

I started in Nomal Windows mode - got the bios screen and the starting windows screen - then the screen went black but I can see the white cursor. I pushed the power button to turn it off.

I restarted in Safe Mode - I re-installed the graphics card driver I had previoulsy rolled back - the desktop icons reamined visible this time - I restarted - it froze on the Shutting Down . . . screen in Safe Mode - I pushe dteh power button to restart it.

On restart - bios screen appeared - it froze for two minutes on the Starting Windows screen - then Black SOD - I can see the white cursor - nothing else.
