Hey guys so first, I'm not too computer literate so please bare with me. So i just re-installed Windows 7 Ultimate 64 Bit and everything went fine. It boots right up and is still a fast machine. But I have 8GB of RAM and it only says 3.99 usable. I have been told that a 32 bit version can make it run at half the RAM but I am 100% sure that i am running a 64 bit version. So does anyone know...
