Question Monitor suddenly turns black

[vw98133]

A few minutes ago, my Dell monitor suddenly turns black. When I push over buttons on the monitor I see a message of no signal. The only way I know to resolve this problem is to reboot my Dell PC. That certainly isn't a cable connection problem. This problem occurs a few times before, not very often though. It is very annoying that happens while I am working on something on my PC.

How to solve this problem?
