Hi again
Things look pretty good since your latest adjustments. The USBPORT.SYS is on the top of most lists - even on average computers. (And, as I mentioned: it's usually USB I/O devices - these aren't the fastest devices by their nature - though each generation is getting a bit faster). Your system is doing pretty well considering all that video/audio coming and going simultaneously with just 4 GB of system memory. I'm guessing you have a fair amount of experience with system tuning (the Power Options tweaks for maximum performance really do help).
Nice work!
Let us know if you have any other questions.
