Do you have integrated graphics (onboard video) as opposed to a dedicated graphics card? A dedicated graphics card uses its own memory whereas integrated graphics uses a chunk of main memory to operate.
It sounds like you might have allocated a gig of RAM for integrated graphics. If you want to adjust the allocation, you should be able to do this through the settings for your video card. Depending on your setup, these settings should be accessible through your Control Panel, either in Display, nVidia or ATI settings.
And how much of your memory you devote to integrated graphics should depend on whether the games you play tend to be more memory or graphics intensive.
