I have a P67A-GD65 (B3) with an i7-2600K, 16 GB of memory, video card with model GTX 560 and a SSD as my main unit. I am using Windows 7 x64. Control Center version is 2.1.012. I went into the UEFI and made sure all settings are default. CC I can shoot well but if I click on any of the profiles of "cool", "Default", "Movie" or "Game." My system crashes. Cannot even use Ctrl + Alt + Delete. I have to hit the reset button on my case. Beyond that, everything works fine. I used the OC Genie button on the motherboard and brought to 4.2 GHz, ran smooth as silk and the temperature never broke 60C.
