Asus anti surge problems!

[TheGuyFromWigan]

Hi
I have had my self built gaming pc for about a month now and I am beginning to get problems with anti surge feature on my Asus M5A78L-M LX3 Motherboard. I will be gaming for about an hour then suddenly the pc will restart and the bios screen pops up with the message:"power supply surges detected during the previous power on. Asus anti-surge was triggered to protect system from unstable power supply".
I have heard that the anti surge feature is over sensitive but I am scared to turn it off in case it fries everything!
Is this the motherboard acting up or the psu?

Psu: http://www.scan.co.uk/products/500w-cooler-master-thunder-b500-b-series-85-eff-120mm-silent-pwm-fan-green-erp-psu

I know coolermaster isn't the most reliable brand but it was all I could afford! I don't have another psu to test 🙁

I had this problem show up this morning when I powered on my computer. This computer is a brand new build, only a month old. The computer has run like a champ with zero issues since I built it. Last night before bed, I shut down my computer like always. This morning I pressed the power button and nothing happened. I pressed it again, nothing. Pressed it again, nothing. Finally after pressing it another time it powered on. That's when the message occurred. "Power supply surges detected during the previous power on. ASUS anti-surge was triggered to protect system from unstable power supply." I knew I had plenty of power because I future proofed this build. I was able to enter the BIOS, save and exit and it booted to Windows 10 just fine. The computer operated just fine. I ran some tests and all seemed fine. I ran an intense game for about 30 minutes and all was fine. So I restarted the computer and no error. I then clicked SHUT DOWN. When I pressed the power button on my tower, nothing happened again just like earlier. After pressing the power button 4 - 5 times, it began to boot up and displayed the error message again. I pressed F1 to enter setup.

At this point, I pulled out my laptop and began reading about this error. To my dismay there was a range of "check this", "try this", "do this", etc. I decided to check the BIOS version. My current version was 0803. I went to the ASUS website, went to my motheboard (ASUS Z170 PRO GAMING), checked for the most current BIOS version and there has been 2 releases since 0803. Most up to date version was 1102. I also noticed under the summary for 1102, it stated "Improved System Stability." I figured ah HA!! GOTCHA!! I downloaded and installed the new BIOS version and the problem has since been resolved. Now when I shut down and then press the power button once, it begins to boot up immediately. Hopefully this is a permanent fix. If the issue resurfaces I will update my post. Hope this solution helps a lot of people! Thanks and good luck.

Best Regards,

Hey guys I was having the same issues as alot of you, my computer was restarting what seemed to me random increments, but it seemed to happen more when I would start to do something that would make the computer work a bit. I read through many different articles and forums, I updated my bios, turned of power surge protector, tested my PSU,even all my temps were rediculously good. Still it would turn off or restart on me. Prior to my computer doing this about 2 weeks ago I took my PC apart slightly and cleaned it and put it back together. I must have not clicked in one of the connectors from the psu to the mother all the way and the slightest movement (like the fans spinning faster) would cause the surge. It clicked when i squeezed it back in and turned back on surge protector on my asus board. Everything is working great and has been for 48 hours I was almost going to buy another PSU good thing I didnt, I almost lost faith in you my sweet corsair HX850 please never fail <3 . Good luck everyone else hope this post helps you out.
