  1. Probably just an older version of CPU-Z. If that doesn't fix it, don't worry about it! :P
  2. Is this a clean install of XP? If not, the OS is probably using the wrong HAL. In the device manager, the "computer" should be listed as a mutliprocessor PC.
  3. Windows XP Home Edition only displays one thread...
  4. yes it is a clean instal and even when i do ctrl+alt+del in performance i only one processor graph....cpu-z version is 1.37
  5. Does the device manager show the computer as being a multiprocessor pc? If not, the incorrect HAL was installed.

    Good call. Most likely the problem.
  7. Is there a way to fix this or to reinstall windows?
  8. Did you check the device manager?

    If it's already stating you have a mutliprocessor pc then you simply need to go into your task manager and select "view/cpu history/one graph per cpu".

    If device manager is not showing a multiprocessor pc the you may need to reinstall XP. You can also try going into device manager, selecting whatever is listed under "computer", right-click on it and select "update driver". Then you'll need to choose the correct HAL, most likely "ACPI Multiprocessor PC". Using this method sometimes renders the OS inoperable, in which case you'll need to reinstall the OS.
  9. I had to re-install windows and now everything is working nicely i see the 2 cpu's thans for the help guys :)
