I think your motherboard or PSU might be the cause, maybe both, but that is an odd problem that I have never encountered before.

What is the PSU and motherboard? are you using an fan controll hubs or light controlers?

my motherboard is Asus h61m-k and my psu is raidmax 535w or 635w,I don't properly remember the w.

i don't know if raidmax has a voltage setting, but check that it's the correct voltage

i recommend you swap the raidmax for a better psu. raidmax power supplies are usually horrible in quality and can quite literally kill your components. try getting a corsair cx450m to replace it.

Hmm, That isn't the great PSU but it should blow up either, sounds like your PC has maybe gone into stand by instead of shutdown, I really don't know much about that kind of error though.

I googled it, it's a known bug with ASUS boards and the BIOS, you'll need to flash the newest version then factory reset the BIOS, that should solve it.

First of all, (before updading the BIOS, thing that you should do anyway), have you got some card reader or USB hub that is connected to power supply? Some of those are so poorly built that give this exact same problem.

[aquila1998]

I have a TP link usb wireless internet adaptor

[Shingouki]

No, aquila1998, i was talking about internal card reader or usb hub, like the one in the image attached.

If they are connected to power supply, they can cause the problem you described.

[aquila1998]

I don't have one

[aquila1998]

how do you reflash bios?

Do you have anything connected to the USB ports. Either external or internal?

 

Flashing your bios is a dodgy game and you could end up with a bricked board or a corrupt OS.

You should only do it if needed.

[Shingouki]

First of all, you go on https://www.asus.com/Motherboards/H61MK/HelpDesk_Download/

Then click on BIOS, and download the latest one, 0801

 

Then, launch the AI SUITE II, it was on the motherboard's CD. In that program you have an UPDATE function, for the BIOS.

 

BUT, i just realized YOU SHOULD NOT DO THAT:

If the motherboard's anti-surge triggers while you're updating, you'll say goodbye to your motherboard. I know it takes only few minutes, but if it happens in the wrong moment, you're without motherboard.

 

Can you test the PSU? Can you test it with another PSU? Are the voltages stable and between the 10% of what declared?

 

IF the power supply is properly working, you can assume it's a software problem, so you can disable the surge protection.
