Sound and crashing problems

Hi - been having sound and crashing problems on my new (used) computer. First, the sound level on some sound effects drops randomly. For instance my dual blades go: WHACK-WHACK WHACK-WHACK whack-whack. The sound level of the music doesn't seem to be affected. Also I'm getting some crashes both on large teams and during things like Rikti invasions. Any time there are a lot of fx flying around. The game freezes and the sound starts looping. At that point I have to reboot or kill the game with task manager. I think that all of my drivers are up to date and it nothing seems to be overheating. Here's my cohHelper thing, and thanks:

I don't see any obvious problems.

But your graphic settings are rather high for that computer.
Have you tried lowering them and see if it still crashes?

I'd try lowering your graphics a bit and also see if you can update your sound driver. That might help too.

It is known that there are an infinite number of worlds, simply because there is an infinite amount of space for them to be in. However, not every one of them is inhabited. Therefore, there must be a finite number of inhabited worlds. Any finite number divided by infinity is as near to nothing as makes no odds, so the average population of all the planets in the Universe can be said to be zero. From this it follows that the population of the whole Universe is also zero, and that any people you may meet from time to time are merely the products of a deranged imagination.
