|Bit confused when you say |
"I have to turn it off and on while clicking on things"
what do you mean by this?
When the monitor goes blank what are you usually doing? playing a game? word processing? surfing the net?
You may want to check a couple of things
1) update your graphics card driver
2) check that your graphics card is seated properly into your motherboard
3) check the temperature of your CPU
4) check your heatsink/fan assembly to ensure its clean and seated correctly
i may be wrong, but when you say your monitor goes black i think it may be a problem with your pc in general rather than your monitor itself. Obvioulsy this is an asumption until you can shed some more light on the matter.
