Hey AZPLAY11 I suggest you go to iobit.com and you can get a program that just came out with a new version Advanced SystemCare 7 Free. If your computer is lagging this program will get it to as fast as possible. There are about a dozen optimization and speed things it does at the click of the scan button and has more features. I won't bore you to death but have been using it for a couple years and even bought the pro version. It keeps my 4 year old toshiba laptop running like new. I think it has well over 100 million downloads in the U.S. alone.
