You should set all options in your UEFI to default and test it out like that. Also, avoid using the stuff like "performance" options. No need. Set it all to default and do a manual OC on your CPU - 4.2Ghz with the 3570k is very simple and safe, and by doing it yourself you will most definitely use less voltage than if you use any sort of auto OC options. I have your CPU, I can help you with OC'ing manually (it's so easy) after you confirmed that everything is OK with default settings.
