Power supply surge detected during the previous power on.

[Stikfigure16]

I had to rebuild most of my pc recently. I've had it up and running for about 6-8 weeks. About a month ago while I was browsing YouTube my computer shut off and turned back on with this message- Power supply surge detected during the previous power on. Asus anti-surge was triggered to protect system from unstable power supply unit. It only happened once and it was fine up until last week when over the span of 20 minutes it happened about six times. Sometimes it would take five minutes to do so, one time it happened ten seconds after the computer turned on. Also while this was going on sometimes the display would randomly shut off and wouldn't turn back on. I'm afraid to turn my computer on now.
My computer specs are- AMD A10-760k cpu, msi radeon rx 480 gaming x 8g graphics card, EVGA 650G2 psu, and an ASUS ROG CROSSBLADE RANGER FM2+ AMD A88X (Bolton D4) SATA 6Gb/s USB 3.0 HDMI ATX AMD Gaming Motherboard. Any help is greatly appreciated. I don't know much about computers and my friend who built it doesn't know what to do, thanks.
