No signal on screen

Hi, I have a lenovo tower attached to a acer monitor. It was working last night and now it's saying No Signal or No Cable I have tried 2 different hdmi cables and even plugged it.into the TV and nothing..

Any ideas?!?

If monitor is connected to a PCI/PCIe graphics card, try removing the card then firmly putting it back - - that often works if the problem was caused by poor connectivity between the card edge-connector and the slot contacts.

If no change, test the card on another PC if you can, that'll tell you whether or not the card itself is faulty.
