Intel Motherboards : Nothing appears after Asrock Logo when Booting

Yesterday I've bought a new PC and successfully installed Windows 8.1.

After a few installations of software (vlc, utorrent...) I've had a blue error screen, after that I can't even get into login screen, windows just won't load "an unexpected i/o error has occurred 0xc00000e9"

I've tried to boot from usb with my windows 8.1, but after Asrock logo it is just a blank screen.

I can't get into safe mode either ( don't know how. F8 won't work ).

I've tried to install windows 10 on usb and oh yes... it booted after almost 2-3 hours of waiting and everything was very slow. I could not install it due to mbr error. Windows sees my SSD and HDD, so they must be fine, right?

So I installed a new copy of windows 10 into my usb ( gpt, fat32 ).

And... now I can't get past black screen after booting. I see basic screen with windows 10 + memory test. I select windows 10 install or recovery tools, I see Asrock logo and... black screen.

My motherboard is Asrock z170 Pro4s.

Help me please, I don't know what to do. 

I am very sorry for my english.

Best,

Erik
