Intermittant video card problem.?

I am having an intermittant problem with my computer video card. Sometimes when I power up the system, the video card causes the monitor to turn completely off (not just power savings mode). The monitor cannot be turned back on unless the computer is turned off and then back on. Just cycling power on the monitor doesn't do it. I don't have any other video symptoms. I don't see anything in the VGA pinout for controlling the monitor power so I'm guessing that I just need to replace the video card. Any other ideas?|||im guessing its not yuor GPU , it cant turn yuor monitor off
