I installed the card on my motherboard, and it burns?
I installed the card on my motherboard, and I plug in the computer. I turn on the computer, and it stays powered on for about half of a second, emitting quiet high pitched electrical buzzes before shutting down and emitting a smell of burning glue or plastic. My power supply is 400 watts, and the computer works fine without the card installed.

I had this problem. Your power supply has cables coming out of it, there should be one cable coming out of it with a black end, you plug that into your video card. Your video card can't run only off of mobo energy, it's not as efficient. Once you plug that black peice in, it will stop the high frequency noise and your card will function well.
There seems to be some electrical problem with the card, or the way you connected it.
First of all, is your power supply a brand one (like Thermaltake) or a generic one? Generic power supplies do not work well with the better range of graphics cards since they don't provide a stable current.
However, if you say you smell burning plastic, the first thing I would look at is the way it's connected to the motherboard and the PSU. Did you attach all the extra connectors from the PSU to the graphics card? The card would have an extra power slot on the top (A 6-pin I think, I had two on my XFX 8800). Is it connected directly to the PSU, or did you use some sort of adapter to be able to plug it in? If you used some sort of 4-pin to 6-pin converter, this could very well be the cause of your problem. If your PSU does not have a 6-pin connector, it might just not be strong enough to handle this card.
If you couldn't find anything wrong with your power connectors, I would try installing the card on another computer and see if it fails there as well. Again, my guess is that your PSU is just not fit to handle that card, cause I haven't seen many 400W *good* PSUs in my life.
