I use firefox, no I usually have Teamspeak and Steam running, When looking up my motherboard when I first saw this problem http://www.gigabyte.com/Products/product-page.aspx?pid=4709#ov I remember reading due to PC architecture some ram will be allocated for some reason it was back in June and I can't remember but here's the link. Edit : I found it * Due to standard PC architecture, a certain amount of memory is reserved for system usage and therefore the actual memory size is less than the stated amount.
