No lights on monitor

When I open my CPU there is no message on the monitor and it is all blank. and the red signal lights on the CPU which is the red light is not blinking. is my motherboard or my monitor? thanks.

It sounds like a motherboard problem. The quickest way to find out is to plug another monitor onto the computer and see what happens.

The culprit could be something as simple as a video card, memory module or expansion card has worked itself a little loose on the board and simply needs reseating.

Either way, it is a job for a qualified technician and we’d suggest contacting your local computer repairer.
