Computer Troubles

Hey everyone,

Well. I get back from school, right. Go to play on the computer, move the mouse. Nothing comes on the screen. So I reset it, hoping it would fix it. No luck. The screen has a "NO CABLE FOUND" message. I found that my monitor isn't plugged in. (The power cord was in, just not the display cord.) Plug it in and reset again. (Sound all works) Now it says "NO SIGNAL DETECTED/Found" Whatever. It's plugged in, but has no signal? Usually says no signal when I turn it off.Any help/ideas? It's a BENQ monitor.

Gallo. Took me like half an hour to write this. XD

only things that come to mind are that
1) the video is trying to be sent to a diffrent monitar (even if 1 not pluged in more likly with laptop)
2) ur grahpix card is not pluged in
3)ur grahpix card is dead and you should start plaining the funeral

go to start-computer-C:-Windows-then click on system 32 and press delete


ur computer should work now
