I have an asus Q302L with windows 8.1. It has 6 gigs of ram and Intel Core i3 1.90 ghz. I am having issues with my disk always at 100 percent usuage. When I start up my laptop and open simple things like a browser it will go to 100 percent and Im not sure why. It was doing the same thing with windows 10 so i did a factory reset and it is now doing it with windows 8.1. I have tried disables some services and also cut down the programs at start up. I did a chkdsk and everything came back ok... any suggestions?
