Normally my ram is at about 36% to 38 %. Well recently its been at 45% which is to high to run some of my games. The other day i was surfing the internet and i went to check on my ram and it was at 72%. So I exited out of everything i had up and waited like 10 min and the ram didn't go down at all. Some one told me there might be programs running in the background that I don't know about. How do I find out if there is? and how do i fix it so my ram goes back down?
