I have a Gigabyte 965P-DS3 Rev. 3.3 board with a E4300 chip. not overclocked. OCZ power supply. I moved computer to hook up new speakers - unplugged old and plugged in new - pushed power button and NOTHING. AT ALL. Checked PS switch plug and it is still plugged in to MB. Power connectiosna ll seem seated well. How do you check anything when you have no power at all. I don't see any led's on the board itself to know if it has power at all or not....
