G531GV Random Shutdown & Reboot

[katego]

Today my G531GV shutdown while it should have slept, then I had to hold the power button down for over 30 seconds to get it to come back on. Then a few minutes later, it rebooted without warning.

I chatted with ASUS support, they say to reset the BIOS. But I have only had this thing for 30 days, and the only thing I have changed in the BIOS is to turn off the startup sound. I have also added a 2TB SSD. The same thing happened right after I added the SSD 3 weeks ago.

Any ideas? I have not updated the BIOS yet, or changed anything significant from stock configuration.
