go into your bios and write the bios rev down that it at now. if it old update it. the error on boot up and wake up is a bios issue.
the reboots at power up is the mb reading your ram spd and setting the speed for the ram. if the bios patches are installed it should read the ram right and let you set the xmp profile once and that it. if you still have issue on waking after installing all the bios updates check your hard drive and ssd drive firmware.
