I installed this video card today along with a new 500 watt power supply. When I turned on my computer first everything was fine. I went to do the bios fix update since I heard this video card tends to cause a computer to crash often before doing the bios update. After it prompted me to restart my computer, which I did and now the monitor won't display anything. The monitor is currently plugged into the new card with a DVI cord. Any help on this?
