Need help getting a nano working. Can't load sketch. Can't burn bootloader.

Got a Nano clone that I've used in projects before, most recently in a stepper motor project. Now when I try to load a sketch, get programmer not responding:

Arduino: 1.8.9 (Windows XP), Board: "Arduino Nano, ATmega328P (Old Bootloader)"

Sketch uses 930 bytes (3%) of program storage space. Maximum is 30720 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.

Problem uploading to board.  See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

This is one of 3 Nano boards I have, and I can load sketches to the other 2. Next thing I did was the Loop-back test and had no problems. After that, decided to try and burn the boot loader again using 1 of the other Nanos I had. No luck (error output in next post)

Any ideas of things to try?

EDIT: One thing I noticed is when I hit the RESET button, the onboard LED flashes dim. The other 2 boards flash bright. Also, I tried burning a boot loader from one good board to the other good board and that didn't work for me either, so I'm not sure how exactly to do that (using one Nano as the programmer to burn the boot loader into the other Nano).

Output when I try to burn the bootloader:

Error while burning bootloader.

Try to put 10uF capacitor between RESET pin and GND pin on Nano which is used as programmer.

From your log:

D:\Program Files\Arduino\hardware\tools\avr/bin/avrdude -CD:\Program Files\Arduino\hardware\tools\avr/etc/avrdude.conf -v -patmega328p -carduino -PCOM6 -b19200 -e -Ulock:w:0x3F:m -Uefuse:w:0xFD:m -Uhfuse:w:0xDA:m -Ulfuse:w:0xFF:m

the parameter -carduino causes that the reset pulse is generated by avrdude at the start of uploading process. This resets programmer Nano and uploading process fails, because programmer Nano skip to its bootloader and expects instructions for self programming.
The RESET-GND capacitor removes this reset pulse so programmer board can continue perform Arduino as ISP sketch.

One thing I noticed is when I hit the RESET button, the onboard LED flashes dim.

Hard to say. It is probably damaged, but if it still flashes it can be good though.

Thank you! This seemed to work for me, but some issues. See next post for loading sketch issues. (Dang character limit of 9000 won't let me post both code snippets in 1 post.)

avrdude done.  Thank you.

When I load a sketch to the "Fixed" Nano, it has a little trouble and gets a verification error. It looks like it writes the sketch, but it doesn't. The following code shows I loaded blink.ino, and I thought it was a success, but when I tried a different sketch, the blink.ino runs (I assume this came with the bootloader that I was able to burn to it). So what is going on here? Can I only load sketches through ISP? That is what I'm trying next.

EDIT: Yes, I can load a sketch through ISP.
