Hello my name is Mrskorpion and i have problem in Skyrim.
I can't play it at all, i dont have any mods or any saves yet.
I have all requirements to play the game and i have Directx11.
What driver version do you have? Go to the Catalyst Control Center and check under Information -> Software. The most current version of the AMD drivers is 12.1 or the 12.2 preview drivers. If you have an older set of drivers, particularly older than 11.11, first thing I would recommend is to update your drivers. Download the http://sites.amd.com/us/game/downloads/Pages/radeon_win7-64.aspx, uninstall the old drivers, reboot, reinstall the new drivers, reboot, see how Skyrim behaves.
Second question: have you tried validating the game cache through Steam? If you downloaded the game rather than installing from a disc, you might have some missing or corrupted files. Validating the game cache with Steam will automatically fix/reacquire those files for you.
Third: what do you have the game's graphic settings set to? Are you running in fullscreen or windowed? Assuming you have the latest Catalyst drivers and you validated the game cache with Steam and you're still having the problem, does reducing the graphics down or running in windowed vs. fullscreen mode change anything?
Finally: how are your GPU temperatures? (You can also find this in the CCC, under the "AMD Overdrive" section, or through a third party program like GPU-Z or MSI Afterburner.) A card running too hot or otherwise teetering on the brink of death can produce weird visual results like this.
