  1. I dont know exactly what is causeing this but from my experiance it sounds like maybe the bios. Look on the asus site see if there is a newer version for your motherboard if there is then on the asus web page for your motherboard see if there is a tool "asus update" will update the bios for you but be carefull do not power off until completed. Or there is the other option that does not fix it but makes it easyer to cope with set an auto save on your work which is probably the first option
  2. You must have installed a software which can not match with your system..
    Try to remember and uninstall that software and also check your system with antvirus.
  3. which psu are you using
