(2 processors)

This is what i see when i look ay "my computers" for someone else:

GenuineIntel
Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz [x86 Family 6 Model 26 Stepping 5]
(8 processors)

This is what CPU-Z shows me:

It's as if 3 of the cores are dead or turned off. i am not aware of
changing any settings that might have caused this..

    Any suggestions will be welcomed as i am puzzled.

note: being puzzled does not make this a special day.

Does anything in http://windows7forums.com/windows-7-support/35801-i7-920-showing-only-one-core.html help?

Pizzadude:
Its possible that some how you have restricted the cores used in either the bios or windows.  Reboot and enter the bios settings and see if one of the options in there is causing the problem.

If the bios is not the problem boot in to windows and press the start button and click help and support.

Type "Selective startup" into Windows Help.

From the results choose Run selective startup using system configuration.

Click to open system configuration.

Click the Boot tab.

Click advanced options.

The box number of processors should be unticked and then click ok.

Then click apply and ok.

Now reboot

PatrickV2:
Nowhere in his post did the OP mention what version of Windows he's running. So perhaps that would be interesting info to add to take away any uncertainties.

Regards, Patrick.
