If you're getting the power save message and have to force restart your computer, it might be the graphics card overheating. I had this problem and discovered there was a small fan built into the underside of my graphics card which was dirty.
Clean all of your fans and the inside of your computer.
I think you have an overheating problem which is either caused by dirt and dust, or possibly settings which need adjustment.
