Ryzen PC crashed now board won't power up.

[atc95]

Hi,

I purchased an R7 1700, Gigabyte AB350M Gaming 3 and PSU and SSD on Friday and seemingly install went fine and had windows 10 running on saturday afternoon. I got home from work today turned on and was using the system briefly until it crashed to a black screen, and now no matter what I try, it will not boot and the motherboard doesn't appear to be receiving any power.

Can anyone help?

Have since taken it out of the case to try and diagnose further but at work now so will be trying later this evening. The PSU is a SX600G (SFF) and I have another of the exact same PSU in my other system. I am planning on swapping over the PSUs to check that but I am already fairly confident it is the motherboard as previously on boot the LEDs on the mobo would flash on. I have posted in customer service and arranged an rma for the motherboard which I will go through with as soon as I can rule out the PSU. I'm just hoping the R7 1700 is still working fine!

Well bit of an update for you, sat in front of the rugby all day saturday with every spare component I had and the ryzen pc on the coffee table. Ran with 1*4gb 2400mhz ddr4 and swapped out the PSU to my other perfectly working SX600G... No power, no LEDS nothing. Then took the 7950 out and used an old radeon 5450 passive card I had lying around... again nothing.

So, switched power supply to a cheapy 450w unit that I borrowed from a mate as I made him upgrade to an EVGA PSU a couple of years back. Running this old PSU with the radeon 5450 and 1 stick of ram seemingly worked. Motherboard booted without any issues and did a few runs of cinebench and seemed stable enough. Then did various different reboots with different hardware and late on saturday got back to my 7950 working with 2x8gb ddr4 and my newly purchased SX600G.

I am clueless as to why the mobo decided it wasn't going to power up for a week, and changing gpu ram and psu didn't fix it at first, but I have since moved one of the RX480s from my main PC into this one to replace the 7950 as it was struggling, and have played 6 or so hours of GTA V this weekend and it is rock solid. I have even looked at ryzen master now and can run 3.8ghz on the 1700 without any issue but looks like 3.9 is a more or less instant crash on my current F2 (AB350M Gaming 3) bios.

all I think think of is a short somewhere. no idea how but with all the component changes happened to free up.

In which case it took its time and the entire time of component swapping it was sat on my mobo box. So far the only problem I have is if I bench at 3.9ghz it crashes whereas I can just about game at 3.9 without crashing (like 10% chance of crashing so far) on stock cooler doesn't go north of 60 celcius according to ryzen master, this is mainly playing overwatch.

Now have memory set to 2666 and all cores at 3.75ghz and it is rock solid.

I'm having the same problem. But the atx version of the board. Shut down last night and just won't power on this morning.

All I can really suggest is trying every possible combination of components. I got absolutely nothing out of mine even when changing gpu, ram, psu and reseating cooler then changed the psu again and it miraculously worked. Probably not what you want to hear but my ab350m board was completely out of action for 2 days before it powered up again, no idea why but it hasn't had any issues since.
