I just got a brand new motherboard and CPU for my system. An AMD 64 4400+ X2 chip. (Yes...I am proud) One thing I was trying to do when I installed Windows fresh on the system is to go back and disable as many processes and services as possible that occur on start up. So after doing this to the best of my ability...I have a few nagging questions. At regular intervals, I will see a 15-20% CPU usage spike in the Task manager. Further use of Sysinternals Process Explorer shows two things. I will occasionally get a spike in CPU usage from Interrupts, and services.exe.

For digital audio workstations (DAW's) it is recommended to make a change in windows to "Optimize for Background Services", as all of the real time effects run as BG services. But it is actually when I do this that I see the biggest effect on CPU usage.  In Sonar 4 PE, I will actually see a 100% CPU usage warning at these regular intervals. (Well sometimes regular) . However in the Task Manager CPU monitor, they will only show up as 20% spikes. And pretty much, these seem to be attributed to 'Interrupts' which I understand to mean some piece of hardware is requesting CPU usage. I just going crazy here. I would at the very least like to discover what it is that is causing this spike in CPU usage.

Let the troubleshooting begin. Thank any and all who help.
