So yesterday my PC was acting funky. I checked and found the ram was at 99% usage (15.9/16.0 in use). I couldn't find anything listed in task manager that was actually using much at all but the PC barely operated, so clearly it was in use. Restarted PC. Still happening. I checked the web and some mentioned GeForce Experience, specifically ShadowPlay as being the culprit. I hard reset the PC and it was OK. I uninstalled Experience and it hasn't happened again. Possibly coincidence. Has anyone else experienced anything similar with GFE? This only started after I installed that new (368?) driver a day or so ago for my GTX970.
