Check your bios to see how much ram your video card is using. That seems like a lot of ram to be missing
If you don't have a discrete gpu you'll be sharing some of it. System Configuration Utility(msconfig). Boot tab Advanced options uncheck Maximum memory Also in bios you can adjust performance of onboard video. 64/128bit etc on some systems.
