Extreme jittering/shuddering on fresh install of home premium

I have installed Windows Vista Home Premium Upgrade on top of XP Pro. It
installed ok, however, within seconds of startup the computer pauses roughly
once every 2 seconds. Its making even routine operations a total chore.

I have noticed, from the task manager, that CPU usage averages 20% (in idle,
when nothing else is being used!!) and Physical Memory usage is at a flat 360
mb (69% flat!). THis is all happening despite nothing else in the system
being used - no other programs running!

What makes it worse is doing ANYTHING, even quickly moving the mouse around
results in CPU usage skyrocketing and the computer slowing down!!!

THis is SO frustrating, everything was just fine with XP Pro - now the
laptop isnt working properly at all.

I would be tremendously grateful for any help that can be offered.

Many thanks,

Did you run the "Upgrade Advisor" before installing Vista? If what you say
about memory is correct, (360 megs of ram is 69% of the total 512 Megs) you
probably need more ram. At least 512 more to run it without the pause.

Windows Vista can run on a PC with 512 megabytes (MB) of random access
memory (RAM), but it runs better with 1 gigabyte (GB). For optimal
performance, boost that to 2 GB or more.

Thanks for the advice.

I added 2 gigs of ram today and the problem has not gone away. The computer
is still juddering and stuttering along. Jittering once every 2 or so seconds
and hogging all of the CPU.

I have heard this could be a problem with the sound card? I have a realtek
adaptor?

THoughts / feelings?

Thanks in advance for your additional help.
