I built my first PC not long ago with 8 Gb of Ram and idle memory useage hovered around 20%. I have a 240Gb SSD and After installing games on Steam and Origin, my hard drive ran out of space, so I transferred a bunch of game memory to an external 1tb hard drive. My CPU useage is only 3% but my Ram memory usage skyrocketed from 20% to 86% on idle and I'm not sure why, is it due to the games? I'm running windows 8.1 64-bit. On task-manager chrome takes the most memory. Is there anything you recommend to get the memory back down or something that could be causing this?
