I'm having this exact same problem, but I am having NO high temps....

Intel E6600 @ 3.4GHz (never gets above 45C, is usually around 30C when it freezes)
G.Skill HZ ram
Sound Blaster Audigy 2
Nvidia 8800GTX

I also get the sound distortion, mainly when I'm in Crysis
videos also make me crash alot it seems....but other times it will just lock up randomly, i have NO clue what is causing it

forgot to put in asus p5n32-e....

ive got all the latest drivers as well

You don't say 'which' drivers you use (I'm presuming the 169.25s as they are the latest whql).. But as you mentioned Crysis, try the 169.44s as they were written for Crysis 1.2 (patched version). You could also try different drivers to the above if the ones mentioned don't fix the problem. Here's a page of drivers for vista:
download from Guru3D.com

I'm currently using the 174.44 betas as they're stable and very fast...

You also mention temps aren't a problem but only gave your chip figures. With a chip over 3GHz your Northbridge is going to be pretty warm too (very warm in fact). Usually they're rated to go pretty high but just check it out if you can. A utility like speedfan or sandra will help you to obtain the temps.
You could also try replacing the sound drivers to ones modified by 'Daniel' See here:

im using the 169.25 drivers...i might try out the beta drivers and see how they work, and thanks for the creative drivers =p....

right now my temps are
core#1 24C
core#2 23C
Mainbord 27C

GFX 53C

I've got fans galore, and one right next to the northbridge...but which temp in speedfan is the northbridge temp?

Sounds like faulty RAM to me.
