I essentially started by using the tweaks from this web site:

I also disabled all Windows updates and I also picked up some tips from various recording magazines but unfortunately I can't remember what they were. The main tips are in the link above.

It's also essential to not install ANYTHING other than your software required for your studio setup and the drivers and patches for that. I don't even have BIAB on that drive. You can run virus and security software for the D drive from the C drive when you have it booted up.

If I need anything from BIAB, I simply boot into the C drive and create it and save it as a midi file, then reboot into the D drive and open Sonar and import it. I usually then render it to audio for further recording.

I then save all my work on an external Glyph 150 GB firewire drive, further isolating it from the main computer in case of a major problem.

Why have 2 computers when you can have 2 hard drives and accomplish the same thing for half the price and half the space ? My home office and my home studio occupy the same room.

Take care and good luck !
