I purchased a XFX HD-675X-ZDFR Radeon HD 6750 1GB 128-bit DDR3 PCI Express 2.1 x16 Video Card from newegg.com for a Dell Precision T-3500 with a PCI Express 2.0 x16. I did some research and was told it would work with a PCI Express 2.1. However when I turn on the computer there is no display but the fan on the video card is running and the computer makes the one beep okay. I have updated the bios on the pc. One thing I noticed is it never showed up in the device manager only the other graphics card (put in for testing) does. I currently don't have another computer to test this on could the card just be bad?
