I have installed a BFG 9800 GT OC+ but can only boot into safe mode and VGA mode.
When trying to set it to any resolution above 640x480, 8-bit,my Princeton 17" flat screen flashes silver briefly when loading Windows and then I get an amber power light and a black screen. If I boot into low res. and it suggests Windows change the resolution, I get the same thing. Same thing when running the install on the drivers. I'm thinking it's trying a resolution the screen can't handle(?) but every time I try anything above the low res. it goes black. I have an ASUS P5NSLI board with an Antec 450W power supply. The power supply has a special pigtail marked for a PCI-E card. Uh, the mobo has DDR2 memory and the video card has DDR3 memory. I just upgraded the BIOS on the mobo with no luck and did the wiping drivers routine with no luck

Did you connect the PCI-E 6-pin connector to the card?
I connected the ne labelled from the power supply and didn't use the splitter that came with the card.
