PC Won't Turn On After Wi-Fi Card Replacement

kangarus

Hello all,

I recently upgraded the Wi-Fi card on my ASRock B560M-ITX/AC motherboard to one with Wi-Fi 6E. Unfortunately, after disassembling and reassembling my PC it no longer turns on. The PSU works (I used the paperclip trick talked about online, and the fans spin up). I've tried reseating all the plugs, jumping it with a screwdriver rather than the power switch, unplugging the GPU and fans. Unfortunately, I am not seeing any fans spin up on these various attempts. Is there any way to confirm if my motherboard is dead? Thank you. The CPU on this board (i5-10400) is from Micro Center if that matters

Does sound like a bad board in that case. I think you've done all you can.

You're seeing a little fan spin? Listen for a click from the PSU, likely a short. From there, disconnect everything possible. Try with just the 24 pin, see if the unit will power on. It won't POST but should power on. Then add the 8 pin CPU power and proceed from there.

Thank you for the advice, I just tried it. I only see the PSU fan spin when I put a paperclip in the correct pins. I am not able to make it spin when the 24 pin is connected to the motherboard. I have not heard any click.

I would connect the 24 pin and 8 pin. Try to short the two power switch pins. Watch the CPU fan closely. You don't see anything? Not even a quarter turn of a fan?

Ok, I tried this (I hope I shorted the pins correctly). Not even a tiny turn of the CPU or PSU fan. For what it's worth, the power light does not turn on even when it should be connected to power. Thanks again.

Power light shouldn't be on unless you have a standby LED. Last thing you could do here is pull the board and test it on a piece of cardboard. Make sure nothing is shorting it out in the case.

Good to know, thanks. I did pull it out on cardboard recently and it's no different unfortunately. I hope I didn't kill it somehow before then.

@PowerSpec_MikeW Thank you so much for the help on this. Sad to hear but it's better than not knowing anything. I guess I'll be getting an upgrade sooner than expected haha. Have a good day!
