First off, the card with pink blocks definitely sounds like its Video RAM is dead. However... since you swapped the card, and it's still giving out only a grey image it might be the monitor's problem. Or, if you tested it using two different monitors, the only other thing that springs to mind if the motherboard not doing its job.

I would suspect the PSU. When they start to go, weird things can happen.

Just my thoughts.

Try a different monitor cable also.

The 4 Possiblities at this moment look to be Monitor, Mother Board, PSU, and distant last due to being fairly new the Video Card.
