|Why is this so difficult to understand? You have 2GB memory but 256MB of that 2GB is currently set aside for the IGP. That means Windows only has access to 1792MB (1.75GB). And not only does the IGP "steal" memory, but it also "steals" some of the CPU power to assist with the graphics. For best performance, it is always preferrable to have a discrete graphics card rather than using the IGP.|
In the BIOS, you can change the setting for the "UMA Frame Buffer Size"...the choices are AUTO, 128MB, 256MB or 512MB. Apparently you have it set to AUTO or 256MB. My guess is it's on AUTO. That means that the BIOS looks at how much RAM you have installed, then alloctates memory to the graphics based on that amount. If you don't do anything all that graphics intensive, try setting it to 128MB, if you're not happy with it, you can always change it back.
You should seriously consider investing in a video card though. If you're not a gamer, you can easily make do with a $20-25 card. For example:
