Question about Computers & Internet
This is most often caused by your VGA cable becoming detached from either the back of your computer or it's connection to the back of the monitor. First, check by unplugging both connections and re-attaching them firmly back into both ends.
If it still displays the no input signal error, then most likely your computer's video card is not transmitting signal to the monitor. So we need to make sure that the video card is working.
If your blue connection in the back of the computer is located near all of the rest of the cables (very close proximity, less than 1 inch apart) then you are using an 'on-board' video card. If you purchase a new video card and place it in one of your lower, available PCI or PCI-Express card slots in your computer and connect your VGA cable to that, you should have video again. But this would be a solution to a defective on-board video card, which if it is still under a warranty should be repaired by your Manufacturer.
Hope that helps.

Are you running an additional Video card? Or are you using the built in one.
You might try cleaning the connector / plugs with acetone from finger polish remover or de=natured alcohol.
Never jam anything on a computer.
If its an add on card, remove it and reboot. Shut down and reinstall card and reboot.
keep me posted please,
