Red AGP LED on ASUS mobo won't go off

I have an ASUS A7N8X Deluxe mobo and I just changed video cards. There is a red LED on the board called "AGP WARN1" that lights when an incompatable card is installed. When lit, the PC will not power on. After changing my video card and attempting to power on, the red LED light came on. I have used this video card in the system before (ATI Radeon 9700 Pro). Now the light won't go off even when I put the original card in that was working an hour ago. The red LED stays on with no AGP card inserted as well. Here's something I found on the web that basically tells me that the light comes on when a certain pin in the slot doesn't make contact with the video card:

"The red LED is driven by a simple hardware circuit and not by the BIOS.
There is a pin on the AGP slot. It is pin A2, and its name is TYPEDET#.
When a video card makes no connection to the pin, it is the video
card's way of saying it prefers 3.3V operation. If a video card
grounds that pin, it means the video card prefers 1.5V operation.
The 1.5V supply is suitable for operating both 4X and 8X AGP rate,
as even though signal levels on the I/O are 0.8V when running 8X,
the actual power used on the chips is still 1.5V. That is why this
pin only has to indicate two voltage preferences."

Well, the quote goes on to show the location of the pin and I have ensured that the video cards and slot are clean and making contact, but the light remains. Is there a way to reset the state of the light to off?

thanks in advance,
Dan

Sounds like the pin may be bent out out of line in the AGP slot?

Can you look in the slot and see if any of the pins are out of line with the others?
