I went to the Intel site and found some chipset drivers that were newer, along with a Realtek (which had shown up in an earlier crash). Pretty much everything is out of the PC except my graphics card. Wait to see what happens now.
Because all indications were that the motherboard had hardware issues, I've gone ahead and replaced it with a different vendor (in case some other incompatibility. I tried recommended actions but to no avail. I will let you know what happens now.
