Actually you have a phenom 2 x2 550 processor.
Either you or someone else tried unlocking the two other cores.
Sometimes this works and other times it dosent.

Reset your bios using the CMOS CLR jumper or go into bios and dissable ACC- Advanced Clock Calibration.

Tou will now have two cores but stable operation.
