Sometimes your monitor will retain the video properties of the last thing plugged in, like if you go from vga to a new dvi card. Try plugging the monitor in to the video card and then power down the system and your monitor for a few minutes. Then power everything back on. See if that works.

It's possible that your video card driver has got corrupted. Try re-installing the driver.
