I am now running Windows 7 64 bit and I am in looking at my system in the control panel and it says I have 4 GB of RAM installed but only 3.25 is usable, this confuses me because I thought since I am running 64 bit all 4 GB would be usable.

Cant use all my RAM
Maybe its your GPU like in that case
My GPU is not integrated though, I have a Geforce 8800 GT 512 MB
Fill in your PC specs so we can see if its you have dedicated graphics. if you do then its using soem of the ram.
Filled in my PC specs with all that I know.
