I was having similar problems but it would crash out to the desktop at random points of gameplay with various games. it turned out that i had some bad RAM installed . I figured this out by running prime95 to do a system stress test and it wouldnt even last a good 15seconds before failing the test.
Did you check the list of tested games for your graphics controller?

If you do not find your games, Intel offers a troubleshooting guide; this may help fixing your issue
This happened to me for a long time and I had given up all hope but the latest drivers had a HUGE gain in all graphical performances on every game I've tried. This was one of the best Driver Updates I have ever seen from Intel in all honesty.
