Thanks,
did you install anything recently? like a software or Windows update, that triggered that issue?
can you try connecting to the monitor using a different cable? like DVI ?
try reinstalling graphic drivers. your motherboard must have an on-board graphic card, otherwise you wouldn't be seeing anything on your monitor :)
