The title explains everything.
I built the computer from scratch Brand new win 7 64 bit os all brand new parts 16 GB ram system only says it has 2.5gb useable. I had this issue before and a fresh OS fixed it but I do not have another OS to work with right now. I Wanna know what causes this issue...
