What does garbled video output mean?

I just got a new hitachi 7k250 sata drive and I was installing windows, but realized I needed a driver disk. I turned the computer off, came back a day later with the disk, but when I turned on the computer I got "out of range" for a few seconds and then some kind of rainbow gradient would lock on the screen. I swapped out the GF4, not terribly sad that it might finally be time to upgrade just in time for doom 3, and put in an old gf1 ddr I had lying around. The computer seemed to boot up fine, I installed windows and right before it was about to boot for the first time the screen went black, but still with a video signal going to the monitor. I restarted and it booted, but the loading screen was sort of garbled and then windows was covered in huge black and white stripes and discolorations. Two video cards both experiencing huge corruption problems with a monitor that had worked just fine and still works fine with my laptop?
 
Check in your BIOS setup to be sure you have enabled the IRQ for video. Also make sure the card is seated properly in the socket (remove and check for dust/debris on the card contacts and in the socket. And make sure the cable is connected firmly but not screwed down too tightly.
. Other than that, boot to safe mode and see if there is something wrong in the setup of the default video driver.
