So, my Skyrim crashes just after bethesda intro. Tried to disable intro and it crashed after few seconds of showing skyrim logo. 

I have no mods installed. I had but because it stopped working, i deleted everything. i manually deleted my old saves and .ini files. (load orders etc.) and everything from steamapp. I have tried to change audio setting to every possible option but none of them works. 
I have reinstalled 3 times now

Thanks in advance for any kind of help!
