    4GB of ram But only 3.25 GB usable


    I have windows 7 64bit edition a quad core processor, and 4 gb of ram. When I go to system in control panel it tells me that I have 4 gb of ram install but only 3.25 is usable, I looked this up on the internet and I found a forum that said Some memory could be allocated to the on-board graphics (which I don't use I have a graphics card) so I went into my bios but I could not find a single setting to turn off on-board graphics, then i read that you can turn on something called "memory remapping" but I couldnt find a setting for that in bios either. Is there anyway of fixing this?

    I have An Abit I-G31 motherboard.

    If you have not setup your BIOS to use the graphics card, you are probably still using the on-board graphics. And that can easily account for the missing MBs. But there must be a way to change your BIOS. I suggest you look again.
    You should also have a look at the Resource Monitor > Memory tab. What does that show for "hardware reserved" - the grey area on the left of the colored bar.

It's funny, because ALL of my RAM was usable some time ago. (I have no idea how long ago this was, but it was on the same OS) I am using Windows 7 Professional 32-bit. I know about the whole 32-bit issue where some say you can't use much more than 3GB. Well, I WAS. I wouldn't be writing this...

What's this all about? Last time I checked system properties it said 5.5 GB usable. Now, today I noticed that my sidebar said that my memory is 40% in use and there's only 1.5 GB available. What's going on here? I was thinking it could be my video card taking the memory, but I didn't change any...
