It occurred once earlier today during operation, then it turned off. Disconnected for a moment and it worked again. Operated for another hour or so but now it fails to start. It powers on correctly and all internal lights and fans function normally, yet it won’t light up, respond to keyboard input, or produce any display output. Occasionally the monitor remains silent, sometimes it seems ready to connect but then rejects the signal. I’ve swapped the D-Pad to the motherboard port, removed the GPU, tested every RAM stick in each slot, extracted the CMOS battery and pressed the power button, unplugged all drives, confirmed nothing is loose. Still no improvement. My focus is now on PSU, motherboard or CPU. I have a spare 650W PSU ready to install after a night’s sleep, but any additional quick fixes would be appreciated. Specs: PSU: Segotep GF750, GPU: RTX 3070, CPU: i5-12400(k?), Motherboard: Gigabyte B660M, RAM: 1x Corsair 1×8GB DDR4, 1x 1TB SSD, 1x 1TB HDD, connected via D-Pad to LG UltraGear 165Hz 32" monitor.
