Windows 10: A new Motherboard hardware problem

Hello, I have a problem. I can't use my Windows 10 Pro key, which I had used once before, on my new motherboard. I upgraded from Windows 10 Pro to Windows 11 before changing my motherboard, and now I have a new motherboard. I still have the key, but when I enter it, it says it couldn't be activated. Is this because I am on Windows 11, because my old motherboard is still linked to my account, or because my key has become unusable? I don't have the money to buy a new Windows, so I want to use my existing Windows again. Is there a solution to this?

:)

 

how do I know if there is a hardware problem?

If you have done all the troubleshooting steps found on the link I would suggest getting your laptop fixed by a certified Dell hardware Technician, you may be having a hardware problem. It is possible that the motherboard is dead if you cannot see any
light indicator anywhere when you power on the laptop.

Choice of memory and motherboard... a bit stuck...

No one who got some suggestions on this one, huh?

I've found out that the Asus M3A78-T needs to be flashed, so then that motherboard is excluded from my list. Which motherboard and memory should I then go for? Any suggestions?
