As of recently my PC (I don't know where to find my specs if I can't access the Control Panel), fails to boot Windows 8, but it does this in a rather odd fashion.
What happens is simple: To start it up I press the power button, after which a screen with a Medion logo appears (This is normal with every startup). Shortly afterwards a circle of rotating balls should appear that indicates that Windows is being loaded/booted, only lately it hasn't been, it stays stuck on that Medion logo screen and nothing happens.

The only F-key that seems to do anything is the F8 key, which directs me to a blue menu in which I can choose three boot devices (Windows Boot Manager and two UEFI's) or where I can Enter Setup. If I select any of these, it goes to a black screen and remains to do nothing. I've already made a recovery USB drive, which shows up as another UEFI option, but this also does nothing when selected.

It doesn't do anything if I press the F5 key, as with all the others, so I'm unable to reach Safe Mode.
The oddest thing though, is that this has happened two times in one week, but after a certain amount of shutting the PC down with the power button (it won't respond to anything else) and fiddling with options, both times it suddenly showed the loading circle of rotating balls, and Windows is loaded nearly instantly.
Now I'm really confused as to what might cause this. I wonder wether my harddrive is fried or if it's some other issue that stops the PC from reaching the drives.
I'm really curious what advice you could give me.
