Pixelation Problem, unsure how to proceed.

Dell / Xps 720 h2c

Specs: Windows Vista 32 Bit
I'll skip the long into as I don't want to waste anyone's time, and get right to the meat of the problem. Basically, I came into possession of a computer from a friend who was making room in his flat. It worked excellently at first, then started failing and I don't know why. Here is the short version of the series of unfortunate events =P

I started getting blue screens a while ago, then after a while, I got graphical issues. I promptly tested the two cards I have and both work fine. I then tried putting in different RAM, and no change in the problem. Now, whenever I boot up, I am immediately greeted by crazy pixelation on the startup message. This pixelation continues into the desktop and I cant really do anything. I dont know whether this is a motherboard issue or not. I want to install WindowsSeven but need to fix this issue first. Any help will be greatly and sincerely appreciated. Thank you community!

It sounds like the VRAM or GPU on one of the cards is going bad or "creeping" off the PCB. Apparently, chip creep was a problem with nVidia's early GeForce 8 cards. Have you tried disabling SLI and running each card by itself? Have you tested all of your x16 slots in single-card mode? Make sure that the edge connectors (bus and SLI hook-ups) are clean. I doubt that the motherboard is at fault here.

You could try baking 8800GTX pie (but ONLY after you've tested the cards in a different PC with a strong enough power supply).

Apparently, GeForce Pie works well.

If you were really concerned about wasting our time, you wouldn't have included the 1st paragraph. :)

I could have made it longer, jam :)

Thank you for the reply, Jack. I have tried removing the cards and running with only one. Moving them between the two pci slots they usually occupy -- but not yet to other occupied slots like the soundcard, etc.

Even if one card is bad, would that cause pixelation at the startup and BIOS screens?

Thanks again!

Well, I figured out the issue. It wasn't quite chip creep, but it involved the gfx cards.
