I factory reset my windows 8.1 laptop ive had for around 2 years. After factory reseting it, it ran fine for a few minutes into i tried watching a youtube video. Internet exploror froze up, and i had to exit out. I got google chrome then, and youtube wouldnt play then either, it kept talking about " if playback doesnt begin shorty... " after this, i factory reset again, and got fire fox instead, and it wouldnt even open, along with the volume mixer. Also, when i try to update the laptop or upgrade to windows 10, it stays at 0kb. Please help!
