Unable to start Gigabyte B650 Eagle AX using the power button. QFLASH can be used instead.
The power pin on the motherboard doesn’t activate the power supply, which stops the system from booting and shows no signs of life. It works when using the QFlash button without a flash drive to load the OS. Recently upgraded with an AMD R7 7700X, Gigabyte B650 Eagle AX, and 32GB DDR5 RAM, I’m still experiencing boot problems. The power button doesn’t work at all, no lights on the motherboard, and no sound from the PSU. Even when connecting the pins directly on the board, nothing happens. Removing unnecessary components didn’t help. After updating the BIOS with QFlash it functioned but didn’t resolve the issue. Occasionally it would boot randomly, but I couldn’t identify a pattern. My old setup worked fine, especially when shorting the 4th pin in the 24-pin cable. The PSU seems to be operating properly. I went to Computer Canada for testing and they couldn’t reproduce the problem, even after swapping the motherboard and trying different RAM slots. They exchanged the board and it worked. Now I’m back home with the new motherboard but still can’t get it to start. Any idea what’s going on? Thanks!
Regarding the button on the case, have you tried it? It's possible it involves wires and connections to the MB. The reset button looks identical, so you might want to swap it with the start button. Alternatively, check the two pins on the MB and connect them together for a moment.
Remove all but one stick of RAM, the GPU, and any SSD drives connected, and check if this resolves the issue. If it doesn't, attempt a breadboarding setup by removing the board from the case, placing it on your motherboard box, connecting the CPU and motherboard power, leaving the CPU installed, adding one stick of RAM, and then trying to short the pins. If neither works, you might have a faulty board.
I attempted to eliminate anything unnecessary, but it didn’t enhance the result. I’ll try testing it outside of the case next time I encounter the problem. For some reason, it isn’t consistent—sometimes it works perfectly, other times it fails completely. Both situations can last for days. Do you think there’s any reasoning behind that?
It seems like a potential issue with the motherboard, possibly due to a loose screw or a cable touching a sensitive area. The problem appears inconsistent—sometimes it functions, other times it causes shorts. It might have damaged the first motherboard and is now affecting the second one gradually. As mentioned before, the breadboard setup should be rechecked after removing the case, ensuring all screws, cables, and connections are secure.
Something comparable occurred to me, from night until morning; I woke up and attempted to start the PC without success, tried numerous solutions, disassembled the machine thoroughly, but ended up finding the motherboard failed overnight. Check if the PSU can power other devices that connect directly to it. It seems the motherboard is likely faulty.
I chose to switch PSU since that was the sole adjustment the shop made, and it seems to have resolved my problem.
