Hi. Both me and a friend have 8gb 1600mhz ddr3 in our systems. Both use windows 7. And both suddenly have a problem of nearing 100% usage. For me this is causing glitching in some games making it very frustrating. Normally with nothing running except cod ghosts and Skype running I sit at around 85% usage. Very so often it rises causing my game to freeze momentarily. Usually ending up in me being shot. Other that buying more ram is ther anything I can do to help? Have already turned off super fetch.
