Computer Not recognising all four cores.

[Yuluthu]

I recently upgrading my processor (Athlon X2 5600 to a Phenom II 945) and it is only recognising 2 of the cores.

I have tried reinstalling drivers, uninstalled the current CPU drivers, and checking the AMD website.

I got a new motherboard, a Gigabyte MA78LM-S2H. I have installed all the drivers for it, so i am sure it is windows-sided.

Device manager sees it has having four processor cores, just nothing else does.

sysconfig>advance options>check box "number of processors," if you already have not, then select 4 if it hasn't already. save>reboot

try that

Disabled the amount of cores i had told sysconfig I had, restarted and it fixed it.

Thanks for helping
