Hello everyone, i'm new around this forum.
I summit, this error has defeated me.

Well, i just recently bought Skyrim from Steam. I downloaded it, and then installed the game. everything went good.
but, whenever I play, every few minutes (let's say about 5 min) the game just freezes up, then "released" after 30 sec, but with an odd screen problem.
The game start to mix up the colors and everything. here are some screenshots to explain what i am talking about :
