I did send my inquiry at AMD's online form and they proposed the following troubleshooting methods:
1.Please perform load default settings of your bios settings and make sure that you are running your system at stock.2.Please install latest AMD chips...
@DomenicoDentice I am at the ASUS repair centre now, I am with my laptop and use it for about 15 minutes, it shows no abnormality till now, but will stay for another 15 minutes
@DomenicoDentice I received the call from their CS, he told me the technicians found no trouble after days of testing. They would like me to collect the laptop and try to demonstrate them how I use my laptop.
