Hi guys!
I Have a problem , I just built new PC.
I reused the my two SSDs with Windows installed on it from my 10700k.
I updated the BIOS and monitor was working and keyboard, mouse.
Bios update was successfull. After booting again it asked to press F1 to got to Bios setup. I did Bios was updated with new version. Boot drive was selected that has Windows installed already from previous PC.
I just exited the Bios and reset PC , and after that no communication with Monitor , keyboard won't light up or mouse.

PC Specs
Motherboard : Asus X870 TUF Gaming Plus WiFi
CPU: Ryzen 9950X
GPU: 4070 Ti 12GB
RAM: 64GB CL-30 6000
SSD drives are from old PC

Any idea what happened?

Bad idea.

With new PC, new, clean Win installation is a must.

So, format your OS drive and install Win anew.

Whatever OS you had on your SSD, is not compatible with your new hardware (e.g different firmware drivers within OS itself).
So, install Win again.

I fixed.
I removed battery from motherboard for 90 sec, then it put it back. PC got booted to Bios, I turned boot drive enabled and cpu fan set to ignore, because I got water cooler. Reset again and it will took 2 min to wake up monitor and booted to Windows.
All working , and don't have to reinstall Windows.
But for now using only 1 stick of memory, will stick another one tomorrow.
Thank you !

It is highly advised that you do. Since running an OS that is meant for completely different PC is a bad idea. Else-ways, driver/firmware conflicts, BSoD, OS corruption would happen sooner or later.

Aeacus is correct.

Even if Windows seems to running okay at the moment, there's a good chance it will start misbehaving or throwing up errors further down the road.

Clean install Windows or just install from existing Windows?
And where to find a key if i will do clean install ? I don't have copy of Windows.

Buy a legit key.

 

[Od86x]

I mean,I bought windows 10 long time ago, last year I upgraded to windows 11 for free.
Do I have to buy key again every time when I lost it?

Do you have a Microsoft account that the license is linked too. Was it OEM or retail?

I'm sorry, I don't know. Anyway to check if license in my Microsft account?
