Another update....

I got my new computer.... installed it and everything ran just fine.... Until yesterday.

I again got the yellow ! in my system manager.

When I went there and looked under the unit for detais, it said could not use this device due to some registry error... reported error 19 I think it was.

Well... I tried., 5 different ESP32 also different models.

Different wires.

Different ports on the computer

Even tried to inject some USB thingie in between

I ran different windows repair tools

I ran CCcleaner

I uninstalled the USB drivers

I reinstalled other USB driverse

NOTHING helped.

I googled a lot, and some suggested that I should go in and delte something like upperFIlter and Lowerfilter for the usb thingis in Registry, so I did... BUT that didnt solve the problem

BUT once there, I noticed something.... the file hhdspmc64.sys

That file caught my interest, because that was part of some serial monitor I installed that required "high level access" ... I dotn remember the name of the serial monitor now, because I deleted it a few days ago.

WEll I went and found the file hhdspmc64.sys under /system/ folder, and deleted and restarted...

BOOOOM

Then suddenly things works again.

I was so relieved, for a while I thought I was losing my mind. I knew that many of the boards had been used/tested a while ago so when they failed I didn't know why. Only when I started over and checked EVERYTHING did I uncover it.

Lesson learned, always try 3 cables, always check USB power with a quality tester and even use a variable load tester in case loading causes an out of spec voltage drop.

Thank you for sharing I will note it down. And thanks to @zander who takes the time to help.

It seems that using hardware is made more difficult these days because even when you think you should be getting a consistent product such as a PC or in recent posts some esp board they are all full undocumented of variations.

The post here mentioning about USB power issues, led me to investigate the USB and it turns out there was something fishy about it 

It turns out it's faulty and I will now return the PC and get another one. 

When I looked under system component settings.. Or what ever it's called... Sometimes.. And only sometimes there was a yellow exclamation signe there.

I also noticed that my wifi (that is connected to a USB port) sometimes dropped out... All though I didn't connect the dots.. Just thought it was bad wifi....

Well... Thanks for leading me in the right direction. 

The other thing mentioned is wiring. If using a breadboard they are well known failure points, try to get off a breadboard and use a sodered solution. If any wires were changed, meter them for possible open circuit. Does the setup still work back on the old computer?

It's something with my setup. 

As mentioned all my hardware worked. All My code worked. When uploaded and compiled on my old computer. But not when compiled and uploaded from my new computer... So something is different, I just can't figure out what. 

The code compiles fine, and uploads fine.

The weird thing is that this code worked just fine on my old computer when I uploaded it, so it must be something about board settings or libraries etc.
