It's the shared memory for the Integrated graphics card, your RAM shares memory to the graphics card, and you are using a lot. If you want more memory, enter BIOS pressing "supr" or "f8" generally and there should be something about shared memory IGP, and put it at 256 MB or so.
If you don't know how to do this, don't risk it. Post if you need help.
i also have the same problem. I had 4 GB RAM but now my laptop is really slow and it says only 256 MB ram is available for use. i can't even re-install win 7 because it needs some 512 MB. Can anyone help me to solve this problem, with entering BIOS and doing all of that is really confusing so i would greatly appreciate it if the explanation is thorough and step by step. Thanks in advance
