I have a PC with an onboard video card, and when I boot it up, as windows starts the screen goes blank and shows no signal. If however I boot up in VGA mode, the screen works fine, but as soon as I attempt to change the screen resolution to something better, the screen again goes blank. Nothing looks out of the ordinary with the Hz or Resolution settings. From what I can tell they are at the screens native settings. I tried this on a different monitor, and it had the same results. Does this mean the video card, on the MoBo is shot? Any ideas?
