I just bought a new AMD Athlon II X4 640 and I installed it and my pc started up fine and running properly but when I go to system propertys/device manager it says I still have my old prossesor(amd athlon II x2 240). I got on CPU-Z and it says i have the AMD Athlon II x4 but says I only have 2 cores...
If I get the correct driver for my cpu will it use all 4 cores?

Specs:
AMD Athlon II X4 640
Asrock N68C GS FX
Corsair CX430
ATI Radion 7770
4GB DDR2 Ram
1.5 TB HDD
