Build "freezing", requiring shutting off by PSU, after changing SSD, cooler and case

[NewAndreas]

Ok, I am puzzled by this issue.  So far I've had this happen 3-4 times after rebuilding my computer when I bought a new case and cooler.

 

What happens is:

• all my screens turn to black (but still seeing a connected device, they don't show "no signal" prompts)
• all fans are still running like normal
• RGB effects are still on, but frozen in the state at which the freeze happened
• and in 3/4 cases audio output is silent, but one time it made the classic "looping a very short segment of audio loudly" scaring the crap out of my girlfriend.

 

It has happened playing The Sims 4 and while watching YouTube, but not while idling.

When it happens, I can't shut off the computer by holding the power button, or by pressing the reset button, so I have to flip the power switch on the PSU.

I have Precision boost and D.O.C.P. enabled, CPU temps are low.

 

The components:

• Ryzen 2700X
• Asus Prime X370-Pro
• 4x8GB G.Skill TridentZ 3200Mhz
• 1070 MSi Gaming-X
• EVGA Supernova G3 750W
• NZXT Kraken X62
• NZXT H440
• SSD Samsung 850 EVO (Boot)
• SSD Samsung 840
• HDD 3TB

Check your Ram, CPU, and PSU

Interesting. I'm definitely leaning to a hardware fault as I've never encountered that the computer won't react to anything other than cutting power.

 

I forgot to add this! When I rebuilt my computer, I changed the boot SSD from the 840 to a 850EVO that I had in a MacBook. I cloned the 840 contents to the 850 using Macrium Reflect. After that, Windows 10 shows a prompt that it is a Windows To Go and that I can't "unplug" the drive that To Go is on...  Maybe this could be related?

this might not do anything,  but you can try cmd.. sfc /scannow. worth a try

Did the check now, didn't discover anything.

Only with Precision Boost at auto settings. Newest BIOS for this board.

At full load it's currently at 3.9 GHz and 61C.Some of this looks a bit funky but I don't know what it means.

did you install the latest chipset driver too?

Ooh, I am one update old. Seems like only the version number for VGA and Package has changed, but I updated anyway.

It just crashed again

 

Maybe I should turn off Precision Boost?

give it go

Ok, so after some more googling when I realized my computer crashed in this when running Asus' Fan Xpert 4 calibration, I started suspecting the NZXT CAM software for my Kraken x62. Found some posts on reddit having the exact same symptoms and I have now uninstalled NZXT CAM and I'm waiting to see if the crashing stops.

 

YES! This was it. After removing CAM, I am now using krakenx to control my pump, and it's working great.
