With a note of appreciation to those on the list who helped, I think my laptop's stability has now improved. I installed Lenovo's System Update utility, which updated various drivers as well as the UEFI and Intel Management Engine firmware on the machine.
The stability issues haven't recurred in the subsequent week.

I just installed and ran CrystalDiskInfo and found it to be screen reader accessible. It reads the SMART data from your hard drive or SSD and reports any drive errors - see my output below.

Thanks, Glen. I'm wondering whether one of the Linux system administration-oriented distributions such as GRML can do likewise. Someone last week also suggested running Windows with the swap file temporarily turned off, to eliminate use of the SSD as virtual memory.

Jason,
Going down the path of the problem potentially being the SSD,
I recommend buying and running a copy of Spinrite.
https://www.grc.com/sr/spinrite.htm
The good news is that it can diagnose and repair most hard drive and SSD issues. The bad news is that it runs in DOS.
Last time I had JAWS for DOS running in the late 90s I was able to get Spinrite to work with it, but that was many moons ago and with the help of QEMM.
The reason that I recommend going down the Spinrite path is to help incriminate or eliminate the SSD.
I think it can do that.

Subject: [Blind-sysadmins] Accessible and effective hardware diagnostic tools? (Linux/Windows)
I have a relatively new laptop that is causing trouble. Symptoms include Windows kernel crashes with various bug check codes reported in the logs, seemingly random program crashes, and Microsoft Outlook data file corruption (even after deleting the .ost files and re-creating them).
This machine has been returned to the manufacturer under warranty, but they failed to find any hardware problem, choosing to re-install Windows as a remedy, which didn’t last.
(i.e., data corruption and program crashes recurred). A local hardware repair vendor also failed to find any issue. To be fair, the BIOS-level tests didn’t reveal any hardware problems when my colleagues at work ran them.
However, Microsoft Memory Diagnostics repeatedly report bad pages. After running the Memory Diagnostic again last week, the system appears to have crashed, then rebooted, reporting drive errors that it “fixed” by returning to a restore point when the repair operation failed. I ran Memory Diagnostics again, this time returning the report below in the Windows logs.
I plan to install Linux on this machine, possibly in a dual-boot configuration, but I want to identify and detect any hardware issue first. Are there additional tools, preferably screen reader accessible, that I could run either under Linux (e.g., a GRML or Arch installation image written to a USB device) or Microsoft Windows that would help to identify the underlying problem – whether it’s a RAM module, the system board, the SSD, etc.? Any other advice would be appreciated, as I’m not receiving quality diagnosis from the vendor or a third party company that I’ve tried.
Here’s the Memory Diagnostics report:
