The title is self explanatory, but basically, I had the windows 8 dvd inside the optical drive, and it said that it needed to restart. Since it was in the middle of installing windows, and I was told that it restarted a number of times in the installation process, I thought nothing of it. After a minute, it didn't turn on. I hit the power switch multiple times, and even held it down for a few seconds, again multiple times. It didn't turn on. I checked all connections again, and even took it apart and put it back together. It still won't turn on! Please help.
