I was playing a game and it started running slowly, so I did a quick check in task manager to see how much of my RAM was being used. It says 80% of memory being used, and some quick addition puts the used RAM at about 2,100mb. My computer has 8bg of RAM in it so I do not understand why it says 80% when it should say about 25% and it never seems to go above 2-3gb. I am using Lenovo i5 intel with 8gb RAM - no graphics card it is some kind of integrated card into the processor, sorry I cant tell you more I basically know nothing about it. I really hope someone can help because I know this computer is more powerful than it is performing. It is 2 years old and has kind of always been like this.
