Windows 10: Computer crash - Will not start

Windows 10 - Version10.0.19042 Build 19042
About two weeks ago, on my HP Desktop computer, I noticed a couple of strange reactions to one of my apps, LibreOffice. When I tried to access anything, writer, calc, etc., a message would pop up stating that the computer had crashed. If I responded by pressing almost any keyboard key, the desired program would open. As the days went on, the computer slowed to a crawl, took several minutes to start, and just did not react normally.
I tried to restore it to an earlier date, but that failed. There were no restore points.
Eventually, I gave up and decided to do a complete computer reset. It had been some time since I did this so I thought it would be good for the computer anyway.
Everything appeared to be going along nicely up till near the end. A message popped up stating the reset had failed and I should try again. Each time I started the computer the same message would pop up and that is the state the computer is in at this time.
When I start the computer, it appears to start normally but then up pops that #&^% message.
I can access BIAS and it looks to be quite normal.
I have not a clue as to what happened, why it happened, or even exactly when it happened. I know where it happened but that doesn't help at all. The computer is dead as a doorknob.
I would like to get things back in order but do not know how to proceed. Is there some way to do this? I am on the verge of calling in a computer tech but thought I would ask here first.
Thanks for reading.

all games crash!

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?
