Audio Trouble. Red X. Driver Problem I think. Help?

So I produce music,
so its not like I can go without sound.

Now i know that the sound card isnt broke.
Well actually I dont,
I just say that to make myself feel better.

But i have a stupid red x over my speaker.
I have a Realtek High Definition Audio installed,
but every time I try,
"The Device cannot be started (Code 10)"

I just need heelpp.
PLEASE!

Other than this,
I LOVE THE LAPTOP =]]
