I have a custom built gaming pc with a gtx 980, msi gaming mother bored, I7 4790k processor and many other other components that are of equal or higher quality but no matter what i do i cannot get my Disk usage below 99% ( Running window 10 ) I have disabled superfetch and windows search i have tried setting my min ram usage is 16gb and my max to double that. I haven even tried disabling the de-fragment option but nothing seems to work. please help any information is appreciated
