So I have an HP Pavilion 17 laptop, with an added 4gb of ram (8 total gb), and I hadn't used it in awhile and had a bunch of unneeded stuff on it and I just wanted to clean it out, so I factory reset it. After, everything is just running slower. i could always easily play games like minecraft and terraria smoothly and now they just take awhile to load up and don't run smooth. On minecraft single player, I stay around 15-20 FPS average, and some random times my FPS will jump to 80-100 for a second or two. I have also noticed that my disk is always full, usually by the "system" task, or "service host-local system". It was like this before I factory reset it and I had no issues. Nothing I've tried has fixed it so I left it alone. I also did update all my drivers after the factory reset and it did nothing. I've dedicated more ram to the games as well, and it hasn't helped. Thanks everyone!
