Random Shutdowns New Build

[falker]

Last week I did my first build in 20 years, things have changed...

I started with:
Ryzen 5 2400g
Corsair DDR4 8GBx2
Asus Prime x370 Pro
Samsung 500GB SSD
EVGA GeForce GTX 1070 SuperClocked Black
Corsair 650M
Windows 10 64 bit

Put it all together without much issue. Booted up and ran fine. However I decided to return the CPU and RAM to upgrade as my choice on the APU (not knowing much about those at the time) was probably wrong. So I bought and installed:

Ryzen 5 2600x
GSkill Trident Z DDR4 3200 mhz 8GBx2 CL14

Everything started fine but after about half an hour while watching a YouTube video it randomly shut down. No BSOD, just screen shut off. Power to the components all still working. Fans on, etc. but the power and reset buttons on the case no longer worked. Had to shut the PSU off and restart it.

I went into trouble shooting mode and have been unable to resolve it. I’ve run Memtest86 which seems fine. Updated all drivers. No go. Even went to the BIOS and set XMP on the RAM appropriately and tried to set the CPU voltage to a constant 1.4V. Nothing works. The computer randomly shuts down like that.

Went to Windows Reliability Monitor and have no errors other than system 41 error, Windows unexpectedly shut down. I’m convinced it’s a hardware issue but I’m not convinced I know what it is.

I’ve run HWinfo64 and temps are fine. It’ll crash with the CPU at 48 degrees.

I cannot fathom what my issue is. Is it my PSU? Motherboard? CPU?

Pleas help to point me in the right direction.

You have to reinstall windows

Can you explain why you think I should reinstall Windows?

Why would that cause my shutdowns? It doesn’t seem like a software issue, there are no errors or BSOD or anything that would lead me to believe that?

new hardware

1. boot into safe mode, use DDU to clean the system off any AMD/Intel/NVIDIA graphics drivers

2. install graphics card driver downloaded from the manufacturer's website

ok. I'll give that a shot later today and report back. Note that the only hardware changes after the original Windows install were the new CPU (still a Ryzen 5) and the RAM. And I did run the AMD driver after installing the new CPU.

I, personally, am leaning towards a hardware issue. Between either the PSU, CPU or motherboard in that order. The system lock (not just a black screen, it cuts the feed to the display, and fact that the Power/Reset buttons on the case stop working) leads me to believe it's one of those?

I should clarify that the PSU is actually the CX650M and I see on the forum those aren't liked around here very much. The new CPU uses 30W more - being my first build in a couple of decades I may have under-spec'd the PSU? In the future I may want to SLI the 1070 to run 4k.

Oh I see, that's one of their entry level psu's....

yes it sounds like a hardware issue if you had to power cycle it

anyways its always good practice to clean off un-used video drivers seeing 2400G is APU so you should clean off the amd/intel crap and install proper nvidia driver from the manufacturer's website.

if you think it's the psu then just get another psu and try

I installed a RM750x PSU and while clearly a much better PSU, it did not solve the problem.

I tried reinstalling Windows and in the middle of doing that the computer crashed and restarted.

I ran Memtest86 all night which claimed my RAM is fine.

Any thoughts on the issue?

Well, it looks like I solved it and it wasn't what I expected. You two were more directionally correct than I was. I managed to reinstall Windows and had it running fine for a while after reinstalling all of the drivers. Then it crashed again as before. I checked the last install that I made and it was Asus Aura Sync. After uninstalling it and restarting to clear the settings on the motherboard it hasn't crashed once. I put it through a AIDA 64 stress test and everything ran fine.

Who'd a thunk?


oh well, I have a better PSU now.

nice, good feeling to get it up and running

Interesting find.
