Laptop stuck on boot logo after shutting down

I bought an Asus X553MA Notebook which came with Windows 8.1 about 5 months ago and until then it's worked fine.

I was working on an essay while on Skype and I leant on the power button by accident.

After turning it back on, it shows the "Asus: In Search Of Incredible" logo, flickers on and off twice pretty fast then hangs.

For some reason, the white, spinning circle spins a lot slower afterwards too.

I can get onto Windows Repair and have tried all the options there, but none of them work.

I've seen a lot of the solutions being to taking out the battery in some way, but the case is sealed completely, so I can't get to it.
