Hi guys, I have a Dell E510 desktop comp. Its running a 3.2 Pentium D with 2 GB RAM, and it came with one of those wimpy ATI radeon X600 Video cards and I wanted to upgrade for better video game play. I went to dell and got one of there recommended cards. The new card I installed is a NEW nVidia GeForce 6800 PCI-E x16 256MB DVI VGA. I first deleted my old video drivers and carefully installed the new card and upon firing it up to install the new video drivers the screen is completely black. The video card's fan fires up and the monitor gets power just is completely black! Im not sure what to do, i've checked the connections of the video card and cables. Any help would be greatly appreciated!! Thanks in advance, Chase.
