Thanks for inquiring, Jay. I continue to go without any crashes, but suddenly started getting BSODs. Several weeks ago I started getting daily BSODs and finally isolated it to a particular USB SD card reader that I had actually been using for years. So I swapped out card readers and no problems for past two weeks.
Just to reiterate, I was initially getting what I call system crashes, where my keyboard/mouse/screen froze and I had to do a restart using the power button.
But the BSODs are different....my screen suddenly turns blue with a message to the effect that a failure has caused my computer to cease operations and that the problem will be reported to Microsoft, after which Win 10 would be restarted. The error message went on to say that it was a "Stop Code" error, and that I could go to www:windows.com/stopcode for more info (I never gleaned much info from that Windows website that I could understand).
Since 20 May, I have had no crashes or BSODs......knock on wood.
But I will heed your advice and do a manual installation of 1903 update.
