Green screen?

I have an HP Pavilion dv4420ca. I've had it for 6 months now, and for the most part it works great. However, for the last three weeks or so I've been having some issues with the screen. Sometimes when I'm working, the screen will flicker oddly, mostly near the top of the screen some lines will appear briefly and the screen kind of, well, flickers. Today I was using it and without warning the entire screen went green. I tried to get the screen to return to normal, and when I pressed 'escape' the audio program that I was running closed, so the computer was still responsive, just the screen was totally green. I turned it off and it seems fine now. This happened once before, about a month and a half ago. I let it slide the first time, but now that it's happened again I'm kind of worried.
Thanks for your help!

Hi Matt,
Thanks for your help. Yeah, I think the computer has usually been on for a while when it happens, and I tend to run a lot of programs at once most of the time too. Also, with it being on my lap there probably isn't the greatest ventillation at all times, although I do try to keep the fan fairly unobstructed. I would try an external monitor, but I never know when it's going to happen. Is there some way that I can test to see if it's overheating, or should I just try buying a cooling pad?

I'm not running too many programs, and it's been on for about two hours now.
The first temperature it gives it 65C, the second is at 51C, and the HDD #0 temp is at 35C

I switched it to the laptop power scheme and now the temp is down around 50, but despite the lower temperature some horizontal lines just flickered across my screen.
