Try an external monitor on it to make sure it is not a fault with the screen or its connections.

Always pop back and let us know the outcome - thanks

Can you take the back off of it? If so, try this:
1. clean all of the dust out.
2. try better thermal paste between CPU and fan
3. inspect all of your capacitors. If the tops are bulging (swollen), they need replacing. if you know how to solder and have soldering equipment, you can fix the monitor for less than $20 by replacing bad capacitors.

I had an HP that did the same thing. Capacitors were bulging. I replaced them and now the monitor works.

Is this only happening when you take the computer out of sleep mode?

Thanks for advice. If I can't find out what may be wrong, I will try to open the back up..

Try this. Hold down the power button for about 10 seconds to force it to shut down completely (or unplug it). Wait at least 10 seconds and press te power button to start it from scratch. If it is a sleep or hybrid sleep issue this may work to get it out of its current state.

You have to be a little bit crazy to keep you from going insane.

Your problem sounds very similar to mine with a desktop
I assembled. My video often goes out and comes back on
randomly for the first few minutes after booting. It is much
more common when the room temperature is low. It has
very rarely done the same thing when waking from sleep.

I'm sure the problem is either in the power supply, the
motherboard, or the video board. I'll probably just replace
all of them rather than experimenting to find out which one
is the culprit.
