Today, my SER9 Pro (which I purchased on 26 September 2025 and has worked perfectly until now) is not starting up. I have tried twice to reset the CMOS by: turning off the mini-PC, disconnecting the power supply and all peripherals, including the HDMI monitor cables, using a pin to press the CMOS reset button for 10 seconds, waiting 10 minutes, reconnecting the power supply and the HDMI monitor cables, turning the mini-PC back on. The power-on light is lit, the fan is turning, but nothing appears on my monitors. Please help URGENTLY. I need this PC to run my business!
