So, back in November 2016 I finished building my new PC..and so on...

 

About a month passed and I suddenly needed to plug in a  USB stick. As I go to plug it it, the connector must have only been about 2cm from the front USB port, my whole PC turns off and restarts.

 

So I check the event log, Kernel-power, event ID 41. Plugged in the USB it worked, took it out plugged it in all is good. Must have been one off.

 

Now roughly 60% of the time i plug in a USB stick, phone cable, other charging cable etc the PC will restart with the same event logged.

 

So its a NZXT H440 case with 4 ports at the front. I have checked all the cabling so i'm sure I didn't knock and dislodge anything during building. I haven't been able to repeat it with the rear USB ports as I cant predict when it will happen.

 

I thought power supply but its solid, even when gaming and getting full draw. The only other thing I can think is static discharge.

 

Anyone else come accross this?or think im on the right lines with my diagnosis?

 

 

Cheers in advance

This sounds like you have a bad connector on that port.  I've also seen junk get jammed in the connector that the power supply sees as a short when plugged in.  A badly jammed USB port, usually on laptops, can short out when things get plugged in.
