So I should take a screenshot of Process Explorer and also a screenshot of the threads and image tabs of whatever is using the most CPU at the time?

Going by what you have seen so far do you think this is a hardware problem or something wrong with Windows?
The person who owns the laptop has said that if it solves the problem then to use the recovery discs that were made at the time of purchase to start fresh.

It sounds like it's a software problem, but not a Windows one. And yes, those are the screenshots I would look to see.

Hi cluberti.
Below are (hopefully) the screenshots you have asked to see.

Almost (good screenshots otherwise) - you will need to run process monitor elevated (right-click, run as administrator) to get the data from the Image tab. This is likely the svchost that contains the event log (which could explain the WMI spikes if something is using the eventing APIs and scanning for information), but it would be beneficial to make sure. If so, I'll give you a command to get a dump of it once we're sure doing so won't crash the machine .

Hi cluberti
Do you think it would solve all problems if I were to just restore the laptop to factory settings using Acer eRecovery Management? I tried installing SP1 for Windows 7 and a few other updates but they have all failed to install so I'm wondering if it might be better just to wipe everything.

Depending on how much time you want to spend, yes, it would probably be easier to do that. Make sure you back up the user's data completely before doing so, of course.

I've already transferred all of his documents, emails and browser preferences onto an external hard drive so I'll get started on it. I'll let you know if the performance improves when I've finished.
Thank you very much for all the help you have given so far, it is appreciated.

Just to let you know that I have restored the laptop to factory settings and after a bit of tidying up it is running smoothly.
Thank you very much for taking time to help with this matter.

No problem, and glad to hear it is working. Hopefully whatever it was won't return.

My wining card was disabling IP helper service. For some reason, it caused the high usage of my CPU. Once I've disabled it, my Windows works perfectly.

Note: It's safe to disable the service if you are NOT using IPv6 protocols.
