A 32bit OS can only address 4Gbs TOTAL...this includes any & everything that uses Memory!
Look at what your graphics card is using in "Shared Memory" & this will more than likely show you where the extra has gone. That's where mine is being used which is good because it's needed by my games.
If you look in Resource Monitor it will show you what is using what for the most part.
My "Usable" RAM is 3325 with Hardware using 771Mbs.
Ok... my graphics card has 256MB dedicated memory... that means it shouldn't dip into my RAM... or did I get that backwards?... as far as I know of the 4GB RAM I have installed 3,25GB should be available to use with a 32bit OS... of that 3.25GB the graphics card uses none as it has its own RAM... that's what I've had explained to me... right or wrong... please help... willing to learn...

Unfortunately, a 32 bit OS can only address a total of four gigs. The 256 megs on your video card is using part of that four gigs. That means 256 megs of you ram is unavailable. It's sitting there in your computer but can't be used because Windows does not have enough memory addresses to map it. There are other devices in the computer that also have memory address space set aside for them. The total address space dedicated to hardware is unavailable to the OS. That's why a system with four gigs of ram can only use 3+ gigs. I hope this is more clear. The only way to resolve this is to switch to a 64 OS - it can address a much larger amount of ram.
