I'm reaching out to the Apple communitie for some help for the first time since I haven't been able to find my answer with Google. Here's what's happen:
I've had to force shutdown my Macbook pro about five times in the past two days become the screen goes "blank" and becomes totally unresponsive. Keyboard input is ignored and closing the lid does not do anything. There are three things that have happened; the screen will either turn white/light gray, black/dark gray, or striped
(I think the light stripes are wider than the dark ones)
. I read that this could be from my CPU or GPU overheating but I don't think they were. Intensive processing was not needed to make this happen.
Any insight as to what's happening would be super helpful.

Thanks for the links. I reset my SMC, PRAM, and NVRAM. Now I'll wait and see if the problem happens again.
The problem isn't related to my Macbook's start-up. I'll be working for an hour and all of a sudden the screen will go solid (or striped) and I have to force shutdown.
My Macbook Pro is a 15 inch, high resolution (not retina), late 2011 I believe. 2.2 GHz Intel Core i7. I've upgraded the RAM (post purchase) from 4GB to 8GB. Also I've upgraded the OS to Mountain Lion.
