PC Wont Load?

[xMedicine]

I've had Skyrim on the PC for about a month now it all of the sudden will not load and is stuck on the loading screen. It's not frozen because the tips change and the model moves. I can't remember doing anything that could cause this. Is there a way to fix this and keep all my saves? I am level 16 and I will not get my stuff deleted a second time! (accidentally deleted one before)
Please help!

Are you using mods? If so how large is the saved game you're trying to load?

My PS3 copy is also having trouble loading lately. I'm not sure what's causing it, or how to stop it.

change the graphics , most of the time my game has problems on loading high graphics . if you don't have any choice , copy your saves and re-install the game
