Alpha did something odd and bluescreened me

Hello!

I installed the alpha yesterday, and managed to open it for a small bit. Checked my settings and then went out and walked on the world a bit. Hell, even started a conversation.
But then both of my screens froze. Completely. After few minutes of waiting, i decided to reboot my computer. And at startup, i got bluescreen.

After this the computer only opens on safe mode, or when i uninstall my graphic drivers (i got AMD Radeon HD 6800 series graphics card). Everytime i have uninstalled them and re-installed (tried a few different versions) the bluescreen always returns on startup.
So basically, everyime i install any drivers for my graphic cards, computer bluescreens on startup! Even after i uninstalled the game!

I’m not tech savy myself, and I came here to ask for help. All kinds are welcomed. What might be the reason, and most importantly, how to fix it!
Thanks already!

Are you able to read the first sentences in bluescreen?
They contain the ERROR which describe the problem.
For example, most time it looks like that…
But your problem sounds like damaged Hardware!
And which driver you’ve installed at last? I mean the driver number.
ATI/AMD do some crazy shit with his drivers in these times/days
