Lately I have been playing games (as you do) and after about an hour of playing I get a message saying that I need to close my game because of ram usage (I have 16gb) when I look at task manager it says that 'service host: local system' is using 11GB of my RAM up and all of my CPU power. This forces me to close my game otherwise my desktop crashes and it just gives me a black screen. No matter how long I wait the process stays at this usage and does not slow down. What is happening? Please help!!
