Sorry, I fixed it please open it again

 

[Jake0402]

Please confirm it if it was fried☹️

I can see it now, seems like blown transistor or regulator for USB3.

Can you tell what is the cause?

 

[Jake0402]

And can these blown transistor is the one preventing my pc to boot?

Cause could be some short or overload of front USB 3 connection, Unplug and try without it. Yes, it could case boot problems if it draws power from something else. There are no spare or unimportant parts.

I unplug it but it's the same, CPU error light showing, Pc turning on without pressing the power button just turning on my psu power up the pc then no signal

Some power problem for sure, maybe a short. You could try to unsolder that chip, got nothing to loose.

Oohh sorry I cannot do that I have no experience soldering. So the main problem is that fried chip? Not my PSU or other components?

 

[Jake0402]

And additional, power button is not working, tried holding it but nothing happen☹️

Look like fried voltage regulator. Which subsequently cause shorted power rail (+5V or +12V I believe) and prevent your PC from turning on.

If that happened during use, RMA the board. Otherwise bring it to repair service.

May I ask once it is repaired, how to prevent this from happening again?

Should check or replace that front USB connector (cable and both ends), check existing and refrain from using unknown USB devices and devices using more than 1A, 5v.

In short - use front panel only to connect working USB devices. And not weird contraptions who can short +5V power rail.

 

[Jake0402]

Uhmmm Front panel?, you mean I should Only use the Pc case usb ports and I should not use the Usb ports of my motherboard?

Recommendations above cover any USB port - also ports in motherboard. You should stick only working USB devices in your computer. We told about front panel only because fried voltage regulator is located directly near USB 3.0 19-pin front panel connector. At least it look like that in one of your photos. You didn't mentioned your motherboard model.

All of my usb devices are connected to the motherboard I do not use the PC case usb port all of them are inserted to the motherboard

 

[Jake0402]

This is my motherboard "Gigabyte B450 Aorus pro wifi"

Fried chip indeed is voltage regulator for front USB 3.0 ports.

 

[Jake0402]

Could it be power surges the reason why it is fried? Because I am not using the usb 3.0 in the front panel and should I change my Pc Case to be sure it wont happen again and buy a power surge protection extension?

 

[Jake0402]

Im thinking the case is broken after that incident
