Artillery Sidewinder X1 - just started a print and the machine made a small pop and turned off, sounded like a fuse. Fuses are fine, switch is fine, power is getting to the power supply. When I was testing for power at the power supply, the motherboard made a popping noise, caught on fire for a second and spit a small thing onto my vinyl floor which burnt the floor a bit. Here's a video explaining the problem and showing the component that burnt out. https://youtu.be/e7kbdgdJGh8Questions:1. Is the problem the power supply or the motherboard? (obviously I'll replace the motherboard but could the problem have come from the PSU?)2. How should I troubleshoot the problem?Thanks!
