I am having trouble upgrading the cpu on my hp touchsmart 300-1025 pc. I want to upgrade the cpu from an amd athlon II X2 240e to an amd athlon II X4 615e. So I install the 615e on the computer then I power on the computer and then after hp logo screen an error message appears saying "error unsupported cpu installed". That does not make any sense. The 615e is an AM3 cpu and 45w just like the 240e. The 615e should absolutely work on this computer. Can somebody please mod the bios for this computer to make the 615e compatible? I would really appreciate it. Oh and before anybody asks, I already tried updating to latest bios from hp and still did not work so the bios needs to be modded.
