Hi, I recently upgraded my CPU to a AMD Phenom ii x6 processor. I was experiencing very slow speeds so i checked task manager and it only shows one core, Device manager also only shows 1 core and so does CPU-Z, any help would be much appreciated. Could this be a power issue as i only have a 400W power supply? Thanks, Nick

That's not a reasonable expected result of a low PSU....
Are you 100% sure you got a Phenom x6? Which chip specifically?
What motherboard do you have? Do you have the latest BIOS?
