What's the explanation for a computer monitor that keeps blinking on and off... sometimes when blinking off, staying off for a prolonged amount of time? Who knows what someone did to this computer...
loose video cable or power cable? Weird screen saver settings set to like 1 min standby mode or something?
if it's not one of these, you have bigger problems.. might need a new video card or monitor.
When I switch the power plug to differents outlets, the monitor will immediately turn on again... then eventually goes black and powerless, then eventually I'll switch to a different outlet, and it will work again for a little while, then go out again. And the process repeats and repeats. Explain that mystery. Weird, no? This things driving me nuts. And I don't feel like going on the phone with Dell for 5 hours for them to just keep telling me... Hold on sir, while I direct you're call to someone else.
