My PH315-51-79P Helios 300 won't start

Tried to turn my laptop on today and the keys and blue light on the side lit up for a few seconds and then turned off. The screen remained black throughout this and the only indication of something happening was the lights and sound of the fan starting and stopping. This process continued in a loop until I held the power button for 5 seconds to stop it from continuing. I cannot currently access my laptop due to this. I did nothing different to cause this issue, I turned off my laptop like normal and when I woke up to go turn it on I experienced this problem. Also the charger is showing as on, so it isn't that. Thanks
