Motherboard not working after shorting out cpu fan header pins with the copper at the end of an rgb strip

Hi all, need some help here. My friend just built a new system and was installing a 4 pin rgb strip. Everything worked fine until the end of the strip which you can cut to resize it touched a cpu fan header. At this point the whole system turned off and would no turn back on. We have tested the psu on a different pc and works fine, tried a different power socket, re-seated ram and reconnected all cables and everything seemed to work fine the day we finished building it, windows was running fine and temps were great. As soon as he installed the rgb strip and accidentally touched the end on the pins everything switched off and would not turn back on. Any ideas how's this could happen and how we could fix it. We assumed that the pins shorted out but are unsure how this damages the whole motherboard.

 

Also the chip circled at the bottom of the mobo got really hot so im not sure if that's got anything to do with it.

 

Specs are as follows:

 

i5 11600k

Arctic Freezer II 280

GTX 1060

Corsair Vengeance LPX 2x4gb 2133mhz

Gigabyte Z490 UD rev 1.0 (BIOS was flashed successfully)

Artic PSU 750W

Lian Li Lancool 215

You could be very unlucky. If after some cooling off the motherboard wont boot it might be broken.

But altho its very much not nice, you could try RMAing it.

 

When i ask for more specs, don't expect me to know the answer!

Not good installing stuff with power on.

Exactly, stuff like that needs to be done with PSU off.
(Altho i do always leave it plugged in so it has a path to ground.)

The led strip wasn't working before when we installed it and powered it on afterwards, for some reason it work when you installed it while the power is on but yup very much agree and very silly mistake on our part
