Okay I ordered Mobo, ram and my friend will sell me his cpu. I'll let you know tomorrow if it works. If you're curious it's ASUS PRIME B550M-A/CSM, GOODRAM 16GB (2X8GB) 3200MHZ CL16 and Ryzen 5 5600x
Hello, I'm back. The issue has been resolved. New Mobo and CPU fixed it. Windows just got deactivated but everything works. Thanks to everyone for your help. It's finally over.
