So two days ago I shut down my computer then unplugged it. So then today I plugged it in and tried to turn it on. It turned on but wasn't starting windows so I unplugged it and plugged it back in to restart it and try powering up again but then it wouldn't even turn on. Their is only one light on and it's the one next to the plugin so the computers getting power but then the light that represents that it has power isn't on and the computer won't turn on. Someone help please.
