Just bought the following components and its gonna be my First AMD Rig, am having tremendous issues getting things to work !

Components:-

MSI B450M-A PRO MAX
AMD Athlon 3000G 3.5GHz Dual-Core Quad-Thread Tray Processor CPU YD3000C6M2OFH AM4 Socket
CRUCIAL BASICS SERIES 8GB 2666Mhz DDR4 CL19 Pc Ram CB8GU2666

2x 3080 Ti
2x 3090
1x 3070 Ti (seems broken i dunno)

I went ahead and connected all cards to risers and then to the board, but am not getting a Signal on my monitor, been trying for nearly 2 days !

Anyone having the same issue of not getting Signal on their monitor ??...

thanks,
