Here are some suggestions for improving your computer setup:
1.
Music XP Optimisations Look at Tuning Tips, Hardware and Services
2.
Creative Optimisations Enter 'SID6516' in search field
3. Remove (power and data cables of) your CD/DVD ROM drive if not used. I found this to be most offensive component ito of noise pollution
For item 2, I don't suggest ACPI change as this requires Windows reinstallation and see Music XP (item 1). BIOS stuff is easy todo and other suggestions are sensible like removing unused cards / devices.
If there are other tweaks, please post them.
Dear Moderator - is it possible to not expire this thread? This is a rapidly growing subject with lots to learn and do.
