I switched to the AM5 system by purchasing 3 new parts;
-Ryzen 7700
-MSI B650 Gaming Plus(all bios versions have the same problem, bios settings is default)
-XPG Lancer Black AX5U6000C3016G-DCLABK 32GB (2x16GB) DDR5 6000MHz
(Other parts work without any problems in the old system, so it is not specified.)
When Windows starts, the wireless mouse cursor stutters, ethernet and USB do not work, Windows is not working properly I need to restart windows to fix it.
But this does not happen every time I open Windows. It happens once out of 5 times when I restart or turn on the PC. When the windows is started properly, there are no problems in stability tests, benchmarks, games.
I formatted and installed clean windows 10, but it didn't fix. Therefore, I do not think it is a OS thing, the problem is hardware.
Which part is the problem? I don't have a chance to test the CPU on another system.
