I have a problem with a CPU upgrade. Former Cpu was Athlon x2 6400+

I got the Msi K9A2 platinum motherboard and the new cpu is the Phenom II x4 965 with the revision C3.

I got the latest BIOS 1.9 and it is all well in the BIOS as it should be, but in windows vista basic 64 bit I only got 2 cores and cpu-z also show 2 cores.

Have anyone a clue what the problem could be?
will aod or core temp still see the other cores ?

Uncheck "Number of processors" if it's checked off.
Reboot.
