@stimakati - don't need to apologize, about not being Technical... but from your question, I wasn't able to discern if it was an integrated GPU, as explained by cdogg, or an AGP/PCI/PCI-e card, so I generalized my answer and asked for clarity... but I see that you more or less got the correct answer... good luck, and keep coming back if you encounter any problems, as this is the best source for solutions...
@cdogg - yes, I know, that aperture size has nothing to do with integrated GPU's mem size, stimakati didn't clearly elaborate on this... that's why point 4 about clarity... but thanks for clearing it up anyhow, as others might benefit from this...
