Hi all, Just upgraded my rig with an AMD Phenom X2 550BE and a gigabyte GA-MA785GM-US2H motherboard. My intention was to unlock the 2 locked cores on the cpu. I bought the CPU from a reputable seller on Fleabay who stated in the listing that it was a guaranteed unlocker. I tried to unlock the cores as per instructions for this board by enabling ACC and changing to Hybrid in the bios. However when I save and restart the pc shuts down but won't reboot. I then need to clear the cmos to get it to boot. Anyone know what I'm doing wrong? The full specs are CPU and MOBO as above 4GB Corsair XMS2 DDR2 800 ram OCZ 500w Modular PSU 2 x 250GB SATA HDD's Geforce 9600 GSO GPU Any help would be much appreciated!!
