usb overcharge detected

[ppolicherla91]

hey so i have had my rig for about 9 months and today it shut down and when i tried to reboot it i got the message that said usb overcharge detected system will shutdown in 15 seconds. I have read up on the subject but everything they have said i have tried and with no results. short of taking the mobo out of the case and running it test bench style on the box i got nothing. I think it might be the mobo itself or the case but can't be too sure. 

 

specs:

i7 4790k 

asus maximus vii formula

corsair 760t

corsair ax 860i psu

32 gb dominator platinum ram

gtx980

 

 

I saved up forever for this build and well i wasn't even thinking of spending money on parts for at least another several years. 

 

Anyone got any ideas for a diy fix?

just keep using it

probably just a 1 time thing

I wouldn't worry about it unless it does it again a few times

Don't worry, as long as something is showing up on the screen it's can't be completely broken.

 

Have you tried to take out all USB devices? And does it happen every time?

I have taken out all usb devices and it happens everytime

its has happened everytime since it showed up the first time all usb out or in

Have you also unplugged the internal headers?

Are yousure nothing conductive has fallen on the MoBo?

yep unplugged all plugs and i actually took out to mobo to check for that.

Ok, can you feel something gets hot around the USB header or the integrated USB sockets?

 

Also plug only in the PSU and RAM, use the iGPU.

just tried both not really feeling heat, both times got the message

Do you have on other PSU to test?

[ppolicherla91]

Do you have on other PSU to test?

Nope

[Stefan1024]

Nope

There are only three things I can imagine:

 

1) The PSU has a dedicated +5V for the USB. If it is not provided the MoBo will think it is shortened and gives you the warning.

 - Testing: Use a multimerter / voltmeter or an USB stick with a build in LED to validate you have power. You should have the same result on all ports.

 

2) One port is shortened because of a bend pin, broken ESD protection diode, or something else.

 - Testing: Use a multimerter / voltmeter or an USB stick with a build in LED to validate you have power. You have to test all ports, including the headers. If you find one that's not like the others you localized the problem.

 

3) The ports are working fine, but the overcurrent protection circuit is messed up and thinks the port is overloaded.

 - Testing: I'm not sure how the circuit will react whenn it detects the overload. Probably it will cut off the power and you can measure it. But it is also possible the port supply is fine while the protection circuit reports an error.

 

4) I don't think it's a pure software based error. But you can try to unplug the PSU and the CMOS battery for one minute.

Welp after turning it on and trying all ports I found out my front usb 3 isn't working and 1 or 2 rear io ports are not working. So I guess it's the mobo?

Yes it looks like it's the MoBo.

This issue should be covered by the warrenty....
