Anything is possible, but if we don't eliminated things one by one... you'll never find your problem.
Just a quick tip, if you are over clocking it's best to try and have power saving technologies disabled. This is due to increased instability when running at the same settings and enabling power saving tech, comapared to when it is disabled. With my i7 920, I need to reduce the base clock and increase the vcore a few notches to have a stable system with EIST.
