Windows 8 computer recently says memory low, and memory usage is 90%+ even with no running programs.

Computer worked fine until recently. Now in task manager even though I have 16 GB RAM, and with programs only 1-2 GB is used, it says 90% memory is used. So whenever I play games, like league of legends, it automatically closes it because low memory. For some reason the cached memory is always 11-13 GB, making only 3-5 GB available. Is this the problem, how do I free up more memory so it doesn't always say 90% memory used?
