This 100% disk usage thing happened after I tried to reinstall a game using a provided tool(Hextech Repair tool for Lol). I tried resetting it multiple times with or without my files being removed but it never worked. All I can do is use save more after it boots like 30 min. What can I do before I send it to service?
