I have an lenovo ideapad s400 and when it turns on it takes forever to go to windows screen (ends up not going) and then starts repairing and failing forever repeating the process . Please help Im 15 and I dont know crap about my problem. I use windows 8.1 my pc is new and it only has usb ports no cd or anything like that would work. Im typing from ps4 so please give me as much info you can.
