Ok. I really need some help. My box will not boot properly since I installed my new graphics card. After the grey apple screen, it just flashes blue and does nothing. I have tried booting using -x, and graphics mode. When I boot using those options, my system stops loading at line: Devf and never goes any further. Please help! I have been reading as much as possible about graphics strings and such, but I'm still clueless how to get to that point.
System: Asus P6T Deluxe V2 - loaded using P6T Deluxe_boot-123 Core i7-920 6GB ddr2 Quadro FX 5500 - 1GB
