I know it's a common question (sorry) but I can't really find a decent answer available out there, it is due to the fact I'm only running a 32 bit OS?

32 bit OS will only utilize 3 to 3.5 gigs of memory total.
What your pic is showing is 4 gigs total installed but only 2.87gb of usable or free memory.
Being that OS uses 256 megs to itself added to the 2.87 gb would give you a total of 3.1 gb total memory usable.
This falls right in to what the normal would be for a 32 bit OS.
You are fine with what you are showing.

Yeah, that sounds about right. Especially if this is a prebuilt OEM machine. On my motherboard, I actually had to change some settings in the BIOS for my Video Card/Memory settings before all 3gb was considered "usable"... before that it only said 2.5gb was usable. My machine is Custom.

If this is a custom machine that you built, I have no idea how to tell you where to look in the BIOS to mess with the settings... all BIOS's are different and it was pretty deep in there for mine, so I wouldn't know where to begin.

Just as I thought, thanks a lot :)
