Do you have your monitor plugged in the back of the pc via the video cable properly?
What video cable are you using? VGA (blue), DVI (white), HDMI (black at the end)
Any beeps when the pc turns on?
Try unplugging the power cable from the back of the pc tower, then hold the power button in the front for 10 seconds while unplugged, then put the power cable back in the pc and turn it on.
Can you try the same monitor on another pc or another monitor on this pc?
You may need to reseat the memory sticks or pci-express video card in the pc if none of the above steps work.
Maybe it was a sleep/hibernate on time issue, or an update or drive update came through or didn't finish but that could be fixed.
Best of luck. Hope this will be resolved.
