Not quite sure what you mean by make model. CPU-Z tells me that the model is the 2AE0, chipset AMD K15 IMC. Also, the only other graphics slots I have are 1x, which I don't think will work with the card
I also have no other computer to test it on.
I just noticed a strange occurrence, the fan on the nvidia card still spins when the card is installed on the motherboard but not connected to the power supply. I think that opens up the possibility that the PSU is not powering the card properly, since I had previously taken the spinning of the fan to mean that the power supply was not the issue.
