Hello
I bought a new setup :
Z490 phantom gaming 4/ac
Intel Core i5 10600K
1*16 Go DDR4
GeForce 1650
The CPU and RAM LEDs light up since first boot and don't stop after 10seconds
Checked & rechecked: 8pin cable plugged in correctly, RAM installed correctly, CPU too (#1pin in the bottom-left corner).
Anyone has any idea ?
