Hesitation every 2 or 3 seconds

After updating from Beta2 to SR1, I noticed that if I move the mouse slowly
across the screen, every 2 or 3 seconds the arrow would pause or hesitate
for approx 1/4 of a second. Also when I open notepad and hold down the "x"
key so that x's start to be written across the page, every 2 or 3 seconds
the x's will pause, again for approx 1/4 of a sec and then continue on for
another 2 or 3 seconds until there's another pause.

This does NOT occur when I boot into Safe Mode w/ networking.

But it DOES occur when I do a "Selective Startup" w/out loading system
services or startup programs (clearing the check boxes in msconfig), even if
I also choose a "base video" startup (msconfig- Boot tab, checking "Base
Video")- arrow.

Using the "net start" command, I found that only 2 services ARE running
during the Selective Startup that are NOT running during Safe Mode. Those
two services are:
- Group Policy Client
- Software Licensing

Disabling Software Licensing service doesn't help. I assume "Group Policy
Client can't be stopped.

What's could be causing these irritating hesitations, and how can I fix it?

Thanks.
 
Just out of curiosity, what type of video card do you have?

I experience this exact same problem using an Nvidia FX5500 video card, and
traced the problem to the native Windows drivers for Nvidia. The cpu was
being flooded with interrupt requests which was causing the 'lag' effect.

By replacing the video driver with the latest Vista driver from nvidia.com
the issue was resolved for me.
