I just built my first computer and wanted to try overclocking but so far all I've managed to do is waste a couple hours of my time. I've got a nice hsf and case cooling and I know both my cpu and mobo are supposed to be good for OC'ing but all I've been able to do is increase the cpu bus a few mhz before my computer won't even post! I think it might be a psu problem. I used a psu calc and it said w/ stock speeds on a generic psu I'd need 20amps on the 12v rail and my psu only has 22amps. Could this be why?
