Spurs ?? Harmonics ??

All the way to the left looks like part of one, then another on screen, then a couple of very little pips then a bigger one, etc.? If they are harmonics would the distance between indicate the fundamental frequency.

Do you have a Uninterruptible backup power supply ?? Can you plug your computer into a more remove outlet in case emissions are conducted ?? Or other peripheral that powers up and down, or goes into standby with your computer being on or off ?

Especially if you use your computer and USB to record data for notes etc, having to turn off the computer is a disadvantage.

I live in a detached house on the hill in my town spaced apart from other houses and do not have much interference.
After many tests I realized that the interference is caused only when the computer is on (I tried to turn on only the 2 monitors, but they do not give interference).
If I turn off the computer and the 2 monitors are on, no error, all tests are passed.
If I turn on the computer (ASUS TUF i9-10900x 10 Core 3.70GHz + nvidia 4090 + 64 GB RAM) the self test gives error 3.
I attach the screenshot
This is something to remember if measurements are to be made.
Probably a $33,000 HP spectrum analyzer under the same circumstances would not give error :))
