That's about all, BIOS wise, that you can do. Do you have a friend whose system you can use to test the card in? Or a different card to try in yours? Is this a new card for you or have you had it awhile? If it's new do you have the power cables attached to the card if it takes them? Also if it's new did you uninstall the drivers for the onboard graphics? Go into device manager and double click on display adapter. If it shows more than one double click on the one you don't want, go to the driver tab and uninstall it. And make sure you have the right nVidia drivers installed. Don't forget the mobo has a 3 year warranty. I just got done sending my ASUS mobo in for a bad PCIe slot. Tell them you're broke and see if they can send you a pre-paid shipping label to pay to send them back the board. That works for the graphics card companies too. A lot of places will pre-pay the shipping, but they won't offer it up front. You have to ask for it.
