HP Media Center monitor goes black randomly

Hp media center M380n
September 17, 2010 at 15:03:38
Specs: Windows 7, 3GHz/2.5
My monitor screen goes black randomly whether computer is idle or I am doing something.
But the computer remains on and monitor power also remains on.
The screen shows up if I turn the monitor power off and then on again. But it comes back only for a short short time, some seconds to at most a minute.
If I position the cursor on an icon before the screen goes black and then I click the program while the screen is still black and if I now turn the monitor off and on again, I see that the program that I clicked did get launched!
What is wrong and how to fix it? Any help is highly appreciated.
It started doing this just yesterday and Windows restore did not fix it. The problem persists in safe mode.

I have HP media center, Pentium 4, 3 GHz running Windows 7 ultimate.

this sounds like a problem with either the video card/chip or the monitor/connections,
1st make sure all the connections are correct and tight. try a new cable and power cable if you have spares.
2nd update your video drivers.
3rd try a different monitor, if the problem still occurs then you know your monitor is ok, if the problem stops then you know its a problem with the monitor and you can return it. just to be sure try your monitor on another machine.
4th lower your screen resolution, you may be running too high for the monitor to cope with.

i hate computers!

Thanks for your help.
The power cable and connections seem to be OK. Changing screen resolution made no difference. All the drivers are upto date.
I am thinking about changing video card and may be trying a new monitor.
One more thing I have noted that if I change the screen brightness to low instead of high, it tends to stick on average 2-3 times longer.
Again, thanks a lot.

sounds like your monitor is the problem, over heating, bad capacitor...try another monitor before playing with the video card...
