8800gt black screen
I just bought a PNY 8800gt graphics card to replace my 8600gt. I plugged it in, and when I turned on the computer, the screen was blank. It wasn't getting a signal from the card. My motherboard (k9n6sgm-v) has an integrated video device (nvidia 6100) and it uses that one instead. I don't think it's a problem, though, because my old 8600 worked just fine there without the integrated graphics ever being involved. When I get to windows, the card isn't recognized. It's as though there was nothing in the PCI-E slot. I've tried flashing the bios to the latest version with no luck. I've also made sure the card is getting enough power (525W PSU). Everything works perfectly, except the card just doesn't appear to be working. It's as if it wasn't plugged in the PCI-E slot at all. Can you help me out here?

Hi Juan016, you have done everything right. I'd say the 8800GT is bad & return it for a refund. Run the 8600GT & the NVIDIA 6100 at the same time. If you check the middle of page 9 in your manual. NOTE: It states; if a PCI-E is inserted the bios will automatically run the PCI-E card. (No need to make a bios setting change).
It also says if you change the setting in the bios to, OnChip and PCIe VGA, the motherboard should run both. Depending what amount of memory you set the NVIDIA to run with. Once in windows check the amount of total memory the NVIDIA or 8600GT reports.
Example: You set the NVIDIA to use 64MB & the 8600GT has 512MB than the NVIDIA or the 8600GT should show 576MB. Its not that uncommon one buys a bad video card.
Reading the manual & windows not seeing the 8800GT tells me the bios did not see the 8800GT card. The card is bad. You’re doing just fine.
