Hello,

just recently upgraded to the following since 2 days ago:

ASUS PRIME B350m-a
Ryzen 5 1600
2x8GB ADATA XPG Z1 2400mhz RAM

along with:
Gigabyte 1060 3gb mini ITX
Samsung 830 SSD
Segate 1tb HDD

Just now I had a strange hard lock up with no BSOD while in windows. Went to grab a coffee and when I came back the PC had hard locked with the CPU fan going full speed/blast. Tried to reset/turn off power from the case button but it wouldn't work. I tried to hold the power button down and it still didn't work. What I had to do is turn the power switch off to get it to turn off.

After waiting a while, I switched everything back on and everything seems to be working fine:
- i've ran a game and virus scan to see if it crashes again under load but nothing.
- I've checked the event viewer to see if there was any issue but there are no entries around the time of the lockup.
- The SSD/HDD are responding fine with no problems
- Voltages in HW monitor seems to be stable, CPU Vcore is at 0.883v and fluctuating between 0.872V and 0.948V. Under the Ryzen CPU the VID seems to be jumping around between 0.887v and 1.141v (is this normal?) [CPU utilization = 4%]
- CPU temp 27c idle, GPU temp 32c (fan speed = 0)
- I have a new PSU arriving today (corsair TX550m) to replace a 5yr old corsair TX550m (2012), but have not experience any other signs/noises that the PSU might be a problem. It is not noisy or hot and is still going strong.
- GPU driver 388.13, this was installed automatically by windows after a clean install, and I have not bothered changing it, as it seems to be running games fine.

The only differences I can remember:
1) the CPU fan felt noisier than usual, I had switched off the PC overnight and it being quite cold today started the PC up. the CPU fan seem to get louder for a few sec then quiet a bit for 30s-1min then go loud again.

2) I had my phone plugged in a front USB port and was charging from there (I unplugged it and am charging it through a USB plug socket)


What could be the cause of the hard crash? I could only consider either motherboard/USB/PSU/CPU or cooler.

Those Adatas are notorious for fitting issues because of the shape of the heatsink. Memory can cause reboots with no error message and all sorts of strange things as it is used for everything. Consider it one of the candidates alongside probably the PSU given the description of the issue. Maybe try pressing them in a bit more, gently.

I would bother. :) The Windows-installed graphics drivers tend to be dodgy. I would download straight from Nvidia and custom-clean install.
 
Yes I do remember a seating issue with the ADATA ram fitting in, triple checked it and reseated more than once and pushed them gently to see that they were fitted in properly and it is very secure now since the new build. I will keep an eye on this.

Going to get new drivers now and clean install option as your said.

Haven't had an issue since but at least having a clue on what it might be will help if it happens again any time.
 
Just an update, PSU has been replaced and drivers updated to latest (388.59) yesterday. Had no problems since the last post until now where I got another hard lock up from just using Firefox. This time however I was able to use the reset button on the case to restart.

Not sure now if its either the gpu drivers or memory. Nothing in the event viewer.
