The refresh rate is set too high for the monitor.
Boot into save mode, uninstall the video card drivers, reboot and reinstall
the video drivers and set the monitor to a refresh rate it can handle.

Monitors with built in protection will blank or turn off if the refresh rate
is set too high......
I see this when switching a monitor to a smaller one and I forget to lower
the refresh rate in the display settings before hand.
