Hi . Here my problem , a week ago i started to get random resets with the messeage " power supply surges detected during the previous power on".
So i Check all connections to the wall/mobo and everything was looking good so i noticed the bios needs an update . I do the update properly then i started to test again ... 2 hours later pc resets again but with no message , no fan spinning . Only lights on the mobo turns on for a while then pc restart again and repeat the loop.

PSU failure ? MOBO ?


Pc Spec evga 1000w g2/asus rampage v extreme/5960x 4.6 htz./ 32gb ddr4 3000htz./x2 980ti sli/corsair h110i/x6 140mm noctua 3000 rpm.

Try telling them that the message is coming up and they'll probably send you a new one. If that new one comes up with the same message maybe it's something to do with your house electricity or another part of the system like the MOBO.

PSU has failed. When it started giving you problems, you should have unplugged the machine and left it that way until the PSU was replaced. Now that you've been messing around with it, there's a possibility that other components may also be damaged.

PSU? Definitely.
MOBO? Maybe now that you've messed around with it...

Consider this: What would have happened if the PSU stopped working while the BIOS was updating? You would have been left with a motherboard that has no way of communicating with what's connected to it, like the CPU, RAM, even things built into the board like the chipset could be affected. This isn't what happened to you, but I'm just giving you a heads up as to why changing flashing firmware is never a good idea when power delivery systems (including the power supply) appear to be having issues.

Here's what I always recommend doing when you get a PSU error:
1) Turn the machine off and unplug it. Press the power button for five seconds to drain all remaining power.
2a) If it's an OEM power supply from the system manufacturer, call them up and see if it's under warranty to be replaced.
2b) If it's a good quality power supply bought directly from a store (online or in person), look up its quality to make sure it's a good idea to buy another of the same one before just replacing it directly. Since I'm here now I'll tell you that the SuperNOVA G2 series is good and there's nothing to worry about in terms of quality. If the replacement also gives issues, you may want to look into a line conditioner for the power outlet in your house.

Since power supplies tend to deliver unstable voltages as they begin to fail, continued use of the machine after a power supply related issue only increases the likelihood of damaging other components in the system. Usually the components that are directly connected to the power supply are the first to go. This includes the motherboard, all drives (except M.2 and U.2), expansion cards that have power connectors on them, and anything else that has a direct connection to the power supply. Usually things like CPUs, RAM, and expansion cards without power connectors are the last to go because there are motherboard VRMs between them and the power supply.

I checked asus forum for advice and some people say there is a common issue in asus motherboard i mean the power surge message . The lastest bios update for my specific mobo by default the surge protection was disable . I notice that and turn it on again.Started to test and Then the strange thing that confuses me ... only mobo leds turning on and also i hear hard disk spin, but no fans spinning no gpu lights .

1) Are you sure that the BIOS update completed without issue?

2) Why are you still messing with it?
