Hi Jim, it looks like you're having problems with your display. Let's see, the screen itself seems OK, so it's probably a loose connection on the box.
Turns out that the graphics card wasn't seated correctly on the motherboard, wasn't screwed in either. All the jiggling had loosened it, and then it simply refused to work.
ten minutes of sweating and reseating later it was all up and working correctly, but by God I was sweating like a pig with the worry over having fried the card by jiggling it incorrectly.
Let that be a lesson to me... never touch another man's graphics card. It reminds me of that sexist Harry Enfield sketch about cars and women...
