Just started making desktops last week and all are new items.
I have a Ryzen 7 3700X and a MSI B450M motherboard and the display does not work on both sockets.
I have replaced the power supply 750 watt and the Motherboard to an Asus B450M.
No display at all with both boards all the lights on the board work but no display the fan rotates and lights up.
Any other tests that I may do?
I think the Ryzen 7 is faulty do you agree?
