32-bit OS can only utilize upto 3GB RAM (XP/Vista/Win7), though thru Device Manager etc, it may correctly show as 4GB installed. However, 32-bit Windows Server Systems can utilize more. Quote:
I installed 64bit Windows 7 yesterday and it shows me 3.5gig usable out of 4gig.

This might be becos 512mb may be used up by the video card - check you bios setting. Do you have a dedicated separate video card or built-in-motherboard kind?
