Install AGP 8X into Dell GX270 tower

Specs: WinXP SP3, 2.8GHz P4/512 MB
I've been trying for a couple weeks to get a new ATI Radeon 9200 8X/4X AGP video card to work in my Dell GX270 Tower. Per Dell, the 270 has a 250 watt PSU with a 1.5 volt AGP slot. I checked the card out in my old Gigabyte K8NS Pro machine and it worked fine. When I connect the 270 directly to the Dell 1704F flat panel using the onboard VGA everything is peachy. When I try using the Radeon, the monitor indicaes it has a signal, but nothing displays. (On Dell displays, if there's no cable connected or no signal, a 3-color block floats around the screen indicating there is no signal). I've run out of ideas and thoughts on how to set the Intel integrated graphics (enabled / disabled) the BIOS video settings (onboard/auto), etc. Suggestions?

This is the typical response from a dual monitor system. The system BIOS setting should be for onboard video off. The system should be displayed on the ATI card as it boots.

When testing the card on a different computer did you test with your flat panel monitor or something else. That card has VGA, DVI and S video outputs. Are you using the same output in both cases?

According to the Dell specs your tower requires a low profile AGP card. Is that what you have? If so, how did you test it in a regular case? Did the card come with two brackets?

BTW, I am wondering where you found a NEW 9200.

Are you sure you are fully inserting and locking the tang at the back of the card?

Are you using the PCI slot directly next to the AGP slot? If so, I suggest you move that card down. That PCI slot may share resources with the AGP slot.

Below is a link to the specs for that Dell model.

The GX270 is what Dell calls a mini-tower. The card fits. It was in the sealed antistatic bag in a sealed ATI box. I got it off ebay. Both monitors were flat panels and both were checked using the DVI output. I didn't have a VGA cable with me when I checked it on the other display (ASUS 21").
@ModifyHardware - I don't understand your answer. The only options in BIOS are Automatic and Onboard.

I know that the Dell is a mini-tower. It requires a low profile (shorter) card. That type of card doesn't fit in a case that uses regular height cards. That was my point.

Some cards advertised as low profile come with two mounting brackets and can be used in either type case. I was just trying to exclude a problem with trying to attach the bracket of a regular height card in a low profile case. It has been attempted.

Found the answer. FINALLY. Dell support said that because the GX270 has a 250 watt PSU, the card won't work. I'm so glad ATI, nVidia, Sapphire, and others so clearly post the minimum PSU needed to run one of their graphics cards in the product specs.
