A couple weeks ago I posed the question here why my system was severely distorting the playback of an orchestral piece I'm working on, particularly rolling timpani. The consensus seemed to be that my P4 2.8 was not up to the task, so I invested in a new Core Duo E8400, which required replacing almost all the rest of the computer's innards with new components, and many hours to assemble, set up, and reload apps.
Now the CPU doesn't even break a sweat on that piece (Task Manager measures 2-12% of capacity). But the piece sounds just as bad as before.
Yesterday evening I read through old posts about distortion, fooled with latency and voices and any software setting that seemed worth trying, all to no avail. It still sounds awful. I tried installing asio4all, which simply turns off the sound. Tried to install a kx driver but there are dozens and the one I tried would not even allow me to reboot the system.
This is getting extremely discouraging, as I am spending all my time fighting with the system instead of composing and orchestrating. If the examples of others did not sound so good (GPO4 orchestration examples), using my same system to listen, I would not believe that GPO could produce professional quality sound.

What is causing the distortion?
System: W2kPro, Sibelius 4.1, GPO Sibelius Edition, Core Duo E8400, 2 GB DDR2-800, Soundblaster Live!, K240KDF phones. (I replaced the SB long ago with an Emu 1212, but it sounded no better and was a pain to use so I sold it.)
