Just take into account, standard desktop OS cannot guarantee a predictable response within a specified period of time (like 3 ms) unlike real-time OS.
Take a look if hardware meets a requirements of your software: maximum latency in image/video processing, displaying video, memory RAM/cache, disk performance etc.
As a second step, try debug run-time system in module Kernel. Additionally you need a high precision timer for logging events when monitoring time line.
Look at How to: Use the High-Resolution Timer <

Wojtek,
Thank you. Those are useful comments.
I recently uninstalled Norton (antivirus) precisely because it was
consuming vast amounts of CPU time. The pausing, however,
has occurred after that time so yes there may be other gluttons
running. I'll check.

make sure you turn off all the helpful stuff on your computer, like
real-time virus protection, parental control, various notifiers which may
be watching you, etc. Try making sure that some resident program is not
taking over your CPU. Get rid of everything what you can get rid of. Look
at the Task Manager with and without BB running. Is there some process
which is periodically kicking in, like a resident virus protector? Perhaps
even try running BB in the "Windows safe mode".
I am saying this because I was getting annoyed with programs like wuauclt
or AcroTray, which were periodically doing something with my computer
without me being quite aware what they were doing. I could see periodic
bursts of activity by these programs. If your machine is loaded to the
rim, such bursts of activity involve swapping to disk, and then you will
see sudden slowdowns.
If the pauses are associated with disk activity, then I would suspect some
resident program is kicking in.
Not sure if this is your case, but who knows.
