After I reinstalled new mb drivers and the video drivers, my monitor is showing the refresh line and the retrace lines! And sometimes it's just hangs up.!
If you're using the latest drivers for the video card, that might be the problem. If you weren't having problems with previous drivers, go back to those. You might also want to try a different video card or monitor to see if the problem persists. It doesn't look like there's any hardware incompatibility between the video card and mobo.
