Dell Demension 4550 and ATI Radeon 1600X Pro AGP w 512MB

I'm attempting to install an ATI Radeon 1600X Pro w 512MB into a Dell Demension 4550.  The machine is not able to complete POST and I have no video at all.  At first I thought the 250 watt PS was not adequate and replaced it with a 500 watt PS.  Same problem, still not able to complete POSTand get the famous 3 green and 1 yellow LED's displayed on back of computer and no BIOS beep codes.  Reinsert the old video card and I get a message stating Boot did not complete last attempt, check point Vcls failed.  Computer then boots up fully with good video.

Dell and ATI not much help except ATI said they would investage sometime in the next 10 months maybe.  Dell said to stay with old video card.

Any ideas?

Do you have an updated BIOS?
This one is the most current:

Have you connected the power connector to your ATI radeon Card?

It's not impossible that the card is defective. Can you try it on another system to verify that it's good?

BIOS has been updated to version A08.

The power connector is connected.

I just installed the card into my Dell Precision 330 and experienced the same problem - don't complete POST.

Going to contact ATI about warranty return.

Thanks,
