Dear Wiley Colons,
On p. 37 above (Jan 21) Blubi states a method that worked to revive his AMD Athlon x2 64 chip based computer. That method worked for me (I have the same chip) when I figured out what version of Windows 10 I had and downloaded the proper "patch" from Microsoft's Cumulative Updates page.
MrCurlyWirly on p. 39 above (Jan 26) offered a fuller step-by-step recipe (with bold formatted steps) which he called Resolution #B and which I actually followed to the letter, except for the filename of the patch file. If your computer is an AMD Athlon 64x2, this ought to work, providing you select the proper patch from the proper Cumulative Update page. A few things will be required: 1. Use of another machine (which you appear to have). 2. A USB memory stick with a few GB of memory on it. 3. A machine that has some GBs free on it. I had to get rid of some stuff on my very full HD (using the command prompt only, e.g. cd TEMP, dir, del this or that) in order to make room for the update. 4. A basic ability to understand and use DOS commands. If you do not have 4. maybe you need a friend to do this fix for you.
The person above on this page of replies who said the fix is "easy" may not be speaking for everyone. The recipe must be followed literally to the letter or you will get an error message or a file-not-found message. But it does work and the actual implementation sitting at your keyboard takes a half hour or less. The computer will spend a good while installing the update.
One thing I will mention, as a person who has forgotten most of what he ever knew about doing command line instructions from the c: prompt, is that if there seems to be a space between a \ or / character and the character after or before it in the command example, it is probably there. You can check by attempting to select it with your mouse.
Good luck!
