i use(d to use) O & O's auto tuner upper one, really helped. (i can give u a registration code if u want)
and then cc cleaner once in a while
and theres another one i cant remember, it gave options for a lot of things that the computer doesnt give options for, helped, free to try and configure your pc how u want for 14 days, and then u have to buy it if u ever want to change anything again.
