So I recently tried to restart my pc because my wifi would always disconnect randomly from my dell xps 8700. When I restarted it stayed stuck on the dell logo and nothing would happen. I couldn't hit f12 or f2 it would just show the logo so I tried taking the little battery out and holding the power button and the putting it back in and starting it but it still didn't work. Took out the ram and tried to restart it but that didn't work either. Then I unplugged my internal hard drive and it seemed to boot up to the windows 8 installation that you get when you first purchase the pc or try to restore it. Can it not be starting up because the hard drive is faulty? I haven't owned the pc for more than 3 years yet the hard drive is faulty? Could there be a fix or another reason it won't start up?
