I have Just reinstalled Windows 64 bit and i am still using 75% or more of my ram just idling all i have installed is my Steam and Advanced systemcare 9 have looked and nothing is using any kind of excessive memory, if i clean ram it goes down slightly but will usually go back up does anyone have any ideals? if i try to play a game it goes past the 4 GB that i have and my computer turns itself off this also happens if i watch a video as well.
