My laptop is stuttering quite frequently recently - every 15-20 seconds usually.
It's an IBM Thinkpad T41. The only hardware changes I have made are replacing one 256 memory stick with 512, and upgrading the 40GB HDD to an 80GB one. However this was quite a while ago, and the stuttering has only gotten serious recently.

With Windows Task Manager open, in the processes window sorted by CPU usage, I notice "System" jumps right to the top whenever there's a spike/ stutter. However, I can't seem to find the process within "System" which is causing this:

Any ideas what else I could do to investigate this?

Did you check

VIEW > SHOW FRACTIONAL CPU usage

If a sub process is using the CPU, it should show then

ADDITIONALLY,

START > run
eventvwr.msc
<enter>

Look under SYSTEM or APPLICATION for errors at the time this showed. I would hazard a guess that you have a bad block on the new harddrive

Thank you gerryf,

I carried out the steps above.

When I select "Show Fractional CPU Usage", I still only see the System process jump up during the spikes, and no sub-process.

And unfortunately I can see no errors in the event viewer either.
