Bios Mods -The Best BIOS Update and Modification Source

First I want to congratulate the forum, very good!
I need your help, I have acer power 1000 and did a CPU upgrade, an Athlon X2 BE-2300, but the system recognizes it as: amd processor unknown.
I updated the BIOS for the Acer Power 1000 modbios R01-B0 With Overclocking By 1234s282, it worked, however the CPU continues: amd processor unknown.
Another thing, the cooler this 0 RPM and speed he is 100% ...

specifications

R01-B2 5C6A1P31

I appreciate your help.

Thank you
