I went to boot up my pc and it turned on and stooped at a2 on mobo boot up and then turned off. I went to put it back on in did not turn on in fact it was not spinning fans for cpu so i unplugged every thing that was not need it then proceed to boot and then i plugged every thing back in got mbr error 1 (master Boot Record) unplugged my hdds and let it boot, it did boot ... I think you get it by now.. would this be a problem with mobo or maybe it short circuit?
