Here are my suggestions:

1. Please properly fill out your computer specs in your user profile. The most pertinent one here is your graphics card. "Intel"? For all we know, this could be an ancient GMA950...
2. What Dolphin version are you using? 4.0 the stable release or a 4.0 development build like 4.0-7216? If you're using a stable release, upgrade to the 5.0 release candidate build or  the latest development build.
3. Try updating your graphics card drivers. (Intel Download Center link for your convenience)
