Black Screen, sound only

Hey guys,

Just recently download the dolphin browser and I'm having trouble playing any games. They show up fine in the emulator, but then I click them only a black screen appears. I can hear the sound of the games, just can't see anything. I can't imagine it's my hardware, as I should be plenty powerful to run this (I think?)

I've also made sure all my video drivers were up to date, including direct x and microsoft c++.

Any idea's on how to fix this?

Thanks guys
