I've bought this Power supply for my new build in Feb 2015 and everything has been working great till the last couple weeks. Now every time  I'm playing a game my computer shuts down or black screens and I occasionally get this error message when my Asus Motherboard bios boots up: 
"power supply surges detected during the previous power on. Asus anti-surge was triggered to protect system from unstable power supply"
 
It seems to be getting worse as time goes on.  Would this mean my power supply is going bad?
