Answer 1

check if cpu-z supports your motherboard

Answer 2

You should have a look in your BIOS settings, to check if any of your processor's cores are disabled. Otherwise, you can just reset the whole BIOS. To do this:

Turn computer off > touch an unpainted metal surface on the back of your computer > open up your computer case > remove the flat, circular, clock battery in the middle of the motherboard for a few seconds > put the battery back in > turn on your computer > check CPU-Z.

Answer 3

What operating system are you using and how was it installed?



If it's XP and you upgraded from a single core CPU, then you forgot to activate the other cores. You need to load the SMP HAL and kernel just once. That will allow XP to detect the other cores and configure them automatically.



The trick is to edit your 'boot.ini' file and temporarily add

"/kernel=ntkrnlmp.exe /hal=halmacpi.dll" to the end of your Windows XP configuration line. Reboot, let XP detect the cores itself, then put your boot.ini file back to normal.

Answer 4

Try resetting your BIOS settings.

Answer 5

resetting your BIOS will not help not one bit trust me. check what board it is and the processor itself cause it could be a 64bit board and you are using a 32bit OS. Meaning you have less functionality on your pc e.g if you have a 4Gb Ram you see its less by either half or a Gig.
