With the new release of battlefield 4, I figured it was time to overclock my CPU since I'm running a hyper 212 fan on the CPU. I used the MSI control center to turn OC genie on which overclocks the CPU to 4.1-4.3(Cant remember specifically). After I used control center I would restart and go in game to have a total system freeze where I would need to do a hard reset in order to get back to the desktop. I tried upping the voltage a bit since I thought it wasn't getting enough power. I tried manually upping the voltage and using auto and it still froze on me. I thought it only happened video games but it also happened when I was just watching youtube videos or doing my business on the desktop. I would also like to add that when playing Battlefield 4 after overclocking, my CPU temp would bounce around 45-55 degrees celsius and my GPU would stay in the low 70's. Is my problem having to do with the voltage or something I'm over looking?

edit: I also forgot to add that when I reset bios to defaults (taking off the OC genie also), the freezing problem would completely disappear.
