Lose the caps. That's shouting. Perhaps your motherboard manufacturer has
an update, so I'd check there first. The onboard graphics may and may not
support OpenGL, and if it doesn't you're not going to be able to play games
which require it.
Got no idea, since you haven't mentioned any of the games you're trying to
run. You need to read the game requirements and compare that with the
capabilities of your system.
