I am getting unpredictable crashes where the computer becomes unresponsive and the image freezes on the screen. I find this failure mode baffling. I don't understand how you can have a crash yet the graphics keep feeding the image to the monitors.
When I say unresponsive, I don't mean the machine is too busy to respond to interrupts, I mean it's dead. The NUMLOCK LED on the keyboard doesn't change when clicking the key, no mouse cursor movement, the screen image is frozen. The board still responds to holding down the power button to power down, and then I power it back up.
This build is maybe 3-4 years old and this problem started in March.
I have disconnected USB devices, the second monitor, removed the GPU. It still crashes. I run Task Manager, HWiNFO, and Resource Monitor. Occasionally the crash will occur when the CPU is 100% or close to it. Occasionally the cores will run hot near 100°C, but many crashes occur when the CPU is running under 50% with cool cores.
The crashes most frequently occur if I am using a videoconferencing app for work, either UberConference, Microsoft Teams, or sometimes Slack (although I've never had a crash using Zoom). But sometimes I can use these for hours with no problem. Some crashes have occurred overnight when I am not there and not running any applications. Two nights in a row it seemed to be when Malwarebytes was running a scan.
I can't find the right conditions to forcibly reproduce a crash.
What should I be looking at? Is this likely a hardware problem (bad board, bad memory) or more likely a software problem, or some combination where the software does something to the hardware that it's not supposed to do?
I have had one recommendation to do a clean reinstall of Windows but I don't want to go through all of that and then find out I have a bad chunk of hardware somewhere.
Windows 10 Home (x64) Version 1903 (build 18362.1016)
Board: ASRock Z97 Extreme6
I removed the GPU for testing and am running on the on-board Intel(R) HD Graphics 4600 [Display adapter]
2 x 8GB of DDR3
