Unforeseen and harsh demise
The issue appears to be with the board, which turns off immediately.
I don't understand how you're handling that RGB cable from the CPU cooler. It seems to be positioned in a way it should be removed. Just leave it out and keep the regular 4-pin fan connector. Avoid touching the motherboard or anything directly on the carpet. Keep parts on cardboard, a box, or paper—paper isn<|pad|> and cardboard are non-conductive, so you won't risk shorts between the pins. First, check if the power supply is working. You can try connecting a short circuit (using a wire or metal clip) between the PS_ON pin and any ground pin in the 24-pin connector. Refer to the provided link for guidance. A simple method is to verify that the PS_ON pin lacks a wire in its row (it was used for -5V, which is no longer common). Once the power supply cables are removed, insert a metal conductor between that PS_ON pin and any COM/GROUND pins in the ATX connector. If the power supply activates, the board should power up and supply voltage to all connectors. Ideally, use a multimeter to confirm voltages. This helps ensure the PS_ON pin is linked to ground via a wire, allowing the supply to run. If you suspect an EPS short, test continuity between the two rows (12V and ground). This can indicate a faulty board or CPU damage. To reset the system, you may need to briefly connect the front panel power switch (PW_SW) and release. Don't expect a built-in speaker to sound; instead, check for LEDs or try booting with a RAM stick in the farthest slot. If it starts smoothly, the fan should run consistently without frequent restarts.
It's me switching on the PSU. RIP The RGB cable from the CPU cooler was at this point disconnected, it's just hanging there. The motherboard is laying on the cardboard box of the new PSU i ordered, but it's dark carpet and a dark box, so might not be as visual. I have actually ordered a new PSU, and both my old and the new PSU result in the same behaviour. Within the video, there is the left side where there is a LED-indicator whether the board has power or not. But that never even lights up in the video. It's the LED-strip of the heatsink lighting up for half a second and then turning off again. I did not use any RAM-stick or anything, as I assumed the first problem would be the MOBO not actually having power. If you supply the MOBO with power, I'd expect it atleast to light up and return error codes for no memory or whatever. Which in this situation not even happens. --------------------------------------------------------------- A colleague has suggested to me that I unscrew the heatsink with the RGB-strip lighting up. If that section lights up but the rest doesn't, it's a probability the problem lies there.
