I have been using my custom computer for about 3-4 years now and it’s just now getting slow,like really slow nothing will respond for like two hours and not even file manager will open quick. My computer has an fx6300,gtx1060 8gb,2 1tb wd blue,16gb ddr3. My hard drives aren’t full and I don’t have a virus I check all the time,this problem has me baffled so any help would be appreciated.
