Just recently I began playing Skyrim again and for no apparent reason it closes itself without warning really fast without warning and goes to the desktop with no signs of any errors occuring. It just straight up goes to the desktop and that's about it... Any suggestions?

A CTD, you say?

Are you running any mods?
Is it always in the same place?
What's your graphics card?

Please post a full dxdiag in spoiler tag and make sure you're running a stock game with no INI modifications, mods installed, or other third-party tweaks.
