PRB: VPC 2004 SP1- VMs freezes on a short periods of time on lapto

I have two Compaq Evo Laptops one is Evo N400c and the other one is N600c
that they have P-III Mobile 850MHZ with 512MB RAM and P-III Mobile 1200MHZ
1GB RAM respectively. I have an annoying problem with Virtual PC 2004 SP1,
which is that, all of my virtual machines (DOS VPCs, Windows VPCs etc.) are
stop responding for a short periods of time (approx 10 to 20 secs.) randomly
while running and then continues as nothing happened (and all Cursors blinks
in abnormal rate in the Guest OSes most of the time!) but this freezing
problem happens so often that I am not able to work. This problem happens on
both of my laptops. Host OS is Windows XP SP2 and the guest OS is also
freshly installed Windows XP SP2 with the latest VPC additions are installed
but even the installation phase was very painfull due to "lock-ups". But the
same virtual machines are working perfectly over my desktop machine which has
the same Host OS Config as my laptops. I have read threads regarding to
SpeedStep causes the problem but even I tried to disable SpeedStep from the
BIOS of my Laptops the problem continued to appear, What is more interesting
that, when I uninstall VPC 2004 SP1 and Install VPC 2004 instead, I have no
such problem! Are there any remedy or information regarding to this issue?

Thanks in advance

Attached screen shot reads "Video Frame Rate : -1680 frames" for a Windows
VM.
I am curious about how to solve this freezing problem really!

 

Have you changed the Windows power management setting to 'Always on'?
