Really quick thing to try that has unstuck computers on odd occasions:

Turn off computer and remove power plug. Remove main battery if its a laptop. Before going any further hold the Power Off/On button down for at least 20 seconds. This discharges the motherboard components which had been known to remember the stuck conditions.

Always pop back and let us know the outcome - thanks

Does the PC go through the usual POST at power on?
Or only get the blinking dash at power on?
Any beeps?

Is it a monitor or laptop screen?

If it is a monitor try and reattach the cable, else I'm sure one of the other users will come up with a solution.
