Updates on the new computer

Ok, after spending almost $400 (with tax) we have a bright and shiny new Compaq Vista.

First impressions, It's not as bad as I thought...just have to get used to things.

The very same speakers that worked on the old Compaq don't work for chit on this one.
I can hardly hear anything even with the volume up on every control I have.

Anyone with any ideas, let me know...also you geeks computer geniuses, I know you have some links to VISTA hacks,,,I'd appreciate it if you'd be able to put me on the trail to fixing this.
