I has a rare problem.
Recently, I bought a Graphic Card NVIDIA GeForce which was installed satisfactorily in my PC (Processor AMD RX Vega11, Motherboard ASUS PRIME A320M-K, power supply Corsair.
The problem is that y plugged the HDMI cable to GPU and it produced a severe electric arc in the videocard and smoke, shortly after I replaced it, and I had a similar problem but this time was when I plugged the cable of ethernet.
All were plugged in a current regulator certificated.
What is the problem and how can I solve in order to won’t happen.
Thank you for your attention.
