    Did you just install it? You may have the wrong kind of RAM.

    Yeah, I got that. Where did the memory come from? When you bought your computer new did it have 256mb and then you installed the 1Gb recently?

    That is what I needed, the memory you bought from EBay is high density memory which most computers cannot use, that is why it is so cheap. Luckily your computer can at least boot and see half of the memory, many will not boot at all with high density. So the memory that you see is half of the 1Gb, which is 512mb plus the 256mb original which comes to 768 then minus the 32mb for onboard video and your total RAM left is 736mb.
