1)Bios is up to date?
2)If you recently changed the motherboard, did you reinstall Windows?
3)Uninstall old gpu drivers via Display Driver Uninstaller, and then install new drivers?
4)Make and model of power supply? If you don't know it, open the case up, and find the label on the unit. EX: Corsair RM650X.
