Hi guys! I've recognized that my CPU is only using one core but it should have two cores. I'm using an AMD Athlon 64 X2 4600+ and i have windows7 if that count but if i remember well when i used xp that used only one core aswell. How could i get the second core to work? waiting for your answers, Thanks in advance.

Try a bios update and check your motherboard supports your CPU.
