No response to power up

[Arclight]

My system

Windows 10 (recent install inside a month)

FX-8320 (1 1/2 years)

Gigabyte 970A Motherboard (5-6 years old)

R9 280X

Ripjaws X RAM (2x4GB) (2 1/2 years old)

Rosewill ARC 650W PSU (1 1/2 years old)

 

I put my computer to sleep the night before this happened. Went to turn it on in the morning and nothing. I have since tested a few things.I have tested the power supply and it powers up the fans and disk drive. I have confirmed the power button is connected to the board properly, and I have tried shorting it out on the board to get it to turn on. I am not sure if there are any other steps to follow. I have read about it potentially being the CMOS battery. Any advice would be helpful.

I will update this as I try new things.

My best guess is that something happened to your motherboard. If you can, test each part individually in a friend's computer or something until you find the problem. If not, probably just try buying a new motherboard, but be ready to return it if that isn't the problem.

Unplug the CPU pin and try to boot. If so, then that either the MB or CPU.

So I finally got the new motherboard. It is a MSI 970A-G43 https://ca.msi.com/Motherboard/970A-G43.html#hero-overview .Same problem as before no response? Could it be a power cable or pin that has failed? Is my CPU also toast? Is my new motherboard DOA? Please help, I am way out of my knowledge base.

Unplug the CPU power pub and try again.

I doubt it's a failed power pin. I've never seen that happen. They all come off rails, so it's more than like a systemic power issue if any.  unplug the CPU power. If nothing happens, get a new PSU.
