I seem to have a problem with a lot of my RAM being used even after a restart with nothing open. I have 16GB and usually about 5-6 free after restarting. Been looking up online and found these supposed "RAM Cleaners", but most require you to pay or seem sketchy. Let me know what you guys think and any info from my system you'd need to help me fix this. Most games are fine, but bigger ones such as SC run like crap.
