I have exactly the same problem as the first poster: sound stuttering on browsing heavy imaged sites (like google maps), and it usually starts if computer is on for a couple of hours. It worsens then, the longer the computer is on, the more stuttering, ultimately even on performing other intensive tasks (not only surfing), though to a far less extent.
I checked temperatures. Seem all normal (GPU is 60 degrees, but that's not abnormal for a GPU is it?). No mem leakage in RAM, happens also if little software is running in the background. It happens on firefox as well as internet explorer and when playing music in foobar as well as in media player.
I have the idea I tried everything, except for a clean reinstall of vista, will try this soon. If that not helps, I'll send it back to manufacturer for repair.

My specs:
Fujitsu Siemens Amilo Desktop Li3740.
Running Win Vista Home Prem. 32bit.
Intel Core 2 Quad Q8300 2.5 Ghz.
4 GB RAM.
NVidia GeForce 9500 GS 512MB.
Realtek High Def. Audio (on board).
NVidia Nforce Networking Controller.
Harddisk: ST3500620AS ATA Device

Any other ideas I could try?

Hope you can give some reactions...
