Reset the CMOS and attempt again. It seems you removed the cooling for the CPU during operation, which isn’t ideal. This action likely didn’t damage the chip but may have caused it to throttle. Your steps probably didn’t impact the motherboard, though other actions remain unclear.
Tested the initial two units, planning to try the GPU and RAM next. Note that the pump is connected to the CPU_OPT header; some sources suggest these boards may fail to power up if no fan-related headers are detected.
It seems the RAM wasn't the problem. I observed that when I turned it on, the motherboard lights would blink once and then stop working. Pressing the power button didn’t shut it down either.
It seems the RAM issue was linked to a power or reset problem. The fact that you didn’t remove the battery from the motherboard but briefly altered the CMOS reset might have triggered the boot failure.
