Motherboard problem... maybe?

Hi everyone. I'm having probably the biggest problem I've ever had while doing on a build and I was hoping someone could help point me in my next direction.

First off, specs...

Fractal Design Focus G White ATX Case
AMD Ryzen 5 1600X
ASRock AB350 Pro4 Motherboard
Corsair Vengeance LPX 16GB (2x8GB) DDR4 DRAM 2133MHz C13 (CMK16GX4M2A2133C13)
Corsair H60 Cooler
EVGA Supernova G3 550W PSU
GeForce GT 730

Samsung 850 Evo 500 GB SSD (disconnected)
LG WH14NS40 Blu-Ray Rewriter (disconnected)


I got everything assembled in the case, but when it came time to fire it up and install Windows, I couldn't get it to power on. After fiddling around and eliminating possible bad components (SSD, Optical Drive, RAM... all of which seem to not be the issue) I was able to get it to power on intermittently. At first I thought it was the power button on the case, since it seemed worked a few times, but then stopped. If I tilted the case, sometimes it would power on, sometimes it wouldn't, so my next step was checking for loose cables. The weirdest thing is though, if I juggle the CPU power connector with the front panel power button connected to the mobo, it will boot without even touching the power button. With it disconnected though, nothing. The 4 pin connector closest to the CPU is loose and will not secure tightly. It wasn't forced on or jammed in incorrectly. I made a video to show what I mean.



The other issue is that when I am able to power it on, I cannot get it to display on any of my monitors. The video card is an EVGA GeForce GT 730 with DVI-D, DVI-I and Mini HDMI inputs. I've tried two different monitors, connecting with multiple DVI cables as well as a DVI to HDMI cable. I don't have an HDMI to Mini HDMI cable to test, but considering the other combinations don't work, I'm pretty sure the issue is not with the card, cables or monitors.

The computer will run for 2 minutes give or take before shutting down. I don't know if that's just because it is idle for that amount of time without any input from me. Again I can't tell since I can't get it to display anything. There doesn't seem to be any excessive heat, or any heat for that matter coming off of it. The pump on the H60 appears to be working and cooling well. All fans are spinning on the PSU, GT730, case and radiator.

I'm pretty much at a loss at this point. Should I consider the motherboard shot and RMA it? I'd appreciate any suggestions. Thanks for reading my long winded explanation.

disconnect the power button and short the pins with something metal, see if it powers up.
 
I'm not entirely sure what happened, but I unscrewed the fan and radiator to check for clearance on my CPU power connector. I moved it around to gave it a little more slack. Seems to be seated a little better now, so maybe that did it. It started right up shorting it with a paperclip. Front panel connectors are on the pins right now and the power and reset buttons seem to be functioning.

All my temps, voltages and fan speeds are off the charts though. I know these can't be accurate since the mobo would literally be frozen, the CPU on fire and the fans blowing gale force winds at the same time. Everything is running cool to the touch, so that should sort itself out after connecting the rest of the components and installing Windows, right?

Take it out of case and build it on a table with just the min parts to boot it up.

Reset BIOS.

Update BIOS if needed.

Add parts and check for stability if good so far.

Put back in case and see what happens.
 
It's all in the case right now and running. Windows is installed. Flashed the BIOS.

The new problem is Windows 10 is only recognising 8 out of 16 GB of RAM as usable. It shows both 8GB sticks in the BIOS, plugged into slots A2 & B2. Virtual Memory issue perhaps?

My first AMD build is starting to become a real pain.
 
Well, RAM issue resolved... sort of. Windows is recognizing about 15.4GB of RAM out of 16, but only if they're in slots A1 & A2, limiting the memory to single channel. Whatever. On to the next issue of the computer refusing to power down after shutting down Windows. It's just one thing after another.
 
Pretty sure it isn't, but at least it's recognizing that more than 8GB is there now.
 
You are probably fighting a losing battle. There are several threads here about Ryzen RAM compatibility.

Might want to give them a read.
 
put 16 gigs,vengence,into computer ran like a dog.all kinds of problems.yook out and replaced with pny memory.problem solved for me.
 
Wound up RMAing the mobo. Got an MSI Tomahawk. Can't even get this thing to post now. I think I wound up with one of the older ones with a manufacture date from around April of last year. I was reading that the ones that first came out needed a BIOS update to make them play nicely with Ryzen, but in order to do that you need an older CPU to actually boot so you can update it. Ridiculous. The headaches continue.
