MB No Power

Good day fellow members,

I have 6 identical system units with these specs

>Gigabyte a320m-s2h

>AMD A8 9600k

>8GB Crucial Ballistix Sport

 

It's almost 4 years old, because of lock down/community quarantine (covid19) those units are in stuck for like 6 months.

Now I'm struggling because it won't power up, literally no power on the motherboard even fan wont spin.

After troubleshooting (cleaned the ram, etc.) I already fixed them but-- after not using it for a day some of units aren't working again.

I'm already tired that time so I did not do some troubleshoot and the next few hours I tried to press the power button again, it did just worked.

 

I hope someone can help me. Thanks a lot.

Buy some new batteries for all motherboards,  they're cheap CR2032 batteries, easy to find. 

 

Disconnect everything from the motherboard except the CPU power cable and the 24 pin cable, connect a monitor to the onboard video (if the cpu has video card built in, i think that one does), try to power by touching the two pins of the power switch in the front panel header with a screwdriver or something metalic. 

If the fan spins or it turns on, you're fine. put back in case and check everything so there's no shorts. 

 

The motherboard has 17 bioses on the download page ... some versions remove Bristol Ridge support ( the family your CPU is in) and later bios versions add support for it back 

You may want to double check what bios version you have, and you may want to check with a spare regular Ryzen cpu if the motherboard works.

I already tried replacing CMOS Batteries still no luck, already tried replacing a brand new PSU(Corsair CV450) still the same. I will try your suggestion next time, I will borrow a Ryzen Processor to my friend. Thank you.
