I have the same problem. My mb died and I replaced it with a gigabyte 970a-d3. Tried replacing the power supply, updating the bios, disabling any wake from LAN or mouse options in the bios and in my network adapter settings, changing the properties of the shutdown button, using the restart button as the power button (switched the wiring on the mb), and changing the system recovery options in settings. Nothing worked and tech support said I need to do a clean install, but I don't want to have to reinstall all my programs. I also updated the mb drivers and graphics card drivers. any suggestions anyone?
