    This might be easier than I thought. Just unplug everything and the 
MB is on a tray I can slide out the back of the computer box. Then easy 
to take off the video chip heat sink and see what might be wrong.

    I know how to test the fix. Turn up the video to maximum and wait 
for a massive failure of both the screen and sound and keyboard. It 
really goes die hard. If this does not happen it is fixed.
