I've just built a new computer (hardware in signature) and everything works except for the graphics card. When I turn the computer on, the graphics card fan spins for a second then shuts off. I tried disabling the onboard graphics in device manager in safe mode and then booting up the computer with the dvi hooked up to the video card but it didn't help. I also installed the new driver for the graphics card but it still won't show up in the device manager. I was very careful installing all the parts and I have inspected carefully to make sure there are no shorts. I am at a loss and would greatly appreciate any help I could get.
updated bios yet? try to switch on the computer with the monitor cable plugged into the motherboards VGA. If it doesnt show any signal then theres a PSU problem. however if it does i'd test it out on another system ASAP
