Power supply surge detected during the previous power on...

Ok so I tried booting my PC up as normal and when I pushed the on button, I noticed it wasn't turning on. I pressed it a few times and it finally started up. When it did I got the message,

"Power supply surge detected during the previous power on.." I've got a photo of the screen below of the message. I know there's tons of threads on this issue, the majority just saying disable the anti-surge but I would assume this is a bad idea?

I've never had this issue before so I'm wondering firstly what the problem was that stopped the PC turning on when I first pressed the button and then whether the power surged because I pressed the button too many times quickly.

Here's my specs below.

Corsair CML16GX3M2A1600C10 Vengeance Low Profile 16GB (2x8GB) DDR3 1600 Mhz
Asus Z97-PRO MoBo
Intel Core i7 4790K
CMASTER HYPER 212 EVO Cooler
Fractal Design Define R4 (Black Pearl) ATX Mid Tower Case
Gigabyte GTX 770 OC 2GB GDDR5 7000MHz Dual-DVI HDMI Displayport PCI-E Graphics Card
Samsung 840 EVO 120GB 2.5 inch Basic SATA Solid State Drive
Seagate 1tb (storage)
Corsair RM 650W 80+ Gold Certified Fully-Modular ATX Power Supply

Thanks for helping.

Sam

Here's all your motherboard manual says about it:

Anti Surge Support [Enabled]
This item allows you to enable or disable the OVP (over voltage protection) and UVP (under voltage protection) functions. This causes the system to automatically shut down when the voltage exceeds the safe range that protects the motherboard's components.

Realistically... you should hit F1, enter the BIOS, save and exit and it should boot up normally. If it doesn't happen frequently, I'd just leave it enabled as that's the default and it's probably somewhat helpful. You don't mention an overclock, but if you raised the voltage too high it's possible that under load you're triggering the OVP and you should either back down on the voltage or disable this and hope for the best.

Also, if you're not connecting your PC to electricity via a surge protector an uninterruptible power supply (UPS), I *highly* recommend you do so. In fact, the manual states that you should. If it's just plugged directly into the wall, you definitely want this enabled and you want to fix that situation.

Thanks for the fast reply. I did press F1 tp enter the BIOS and then saved and exited straight after. Nothing is over clocked, it's all at default values.

Currently I think the PC is actually plugged in an adapter so I will plug it directly into the wall for now and look at surge protectors.

But I've had the PC setup like this for about 10 months now and I've never experienced this issue before.

What would the cause do you think that prevented it from booting when I first attempted to switch it on?

I was recommended that PSU on here as well lol When you say look at my power supply voltages, what specifically do you mean? In the BIOS? If so what should I relate the figures too?

First, the word 'surge' on your monitor has a completely different and unrelated meaning to the word 'surge' in surge protection. Absolutely no relationship exists between an Asus surge and what a UPS or surge protector do.

Second, same hardware that detects a surge is also what HWInfo and BIOS read. Voltages may be just fine. But that other 'power system' component might be defective. Voltages must be measured with a digital meter to confirm those voltages, to calibrate hardware read by HWInfo and BIOS, and to report on other 'power system' hardware..

Another problem could also explain that Asus surge message. Therefore what those numbers are (even if within ATX specifcations) may be reporting some other defect. Useful is to only report relevant numbers. Many YouTube videos do not demonstrate how to obtain all relevant numbers.

Thanks for your explanation. Although I'm afraid I'm not sure what it is I need to do from what you've said?

Get a digital meter, request some instructions, and perform minutes of labor. Report those three digit numbers to learn what is happening in the many components of that computer's power 'system'.
