Hi,
I reassembled a PC with this motherboard and an I5-9600KF yesterday and it did not start.
After classic research, memory, power supply, processor, clear CMOS ...
I connected it while flying without any connection and I discovered that it was by connecting the network that it did not start.
If I disconnect the network, I can start without problem and reconnect my network afterwards.
I thought it was an electrical problem with the ground but no, if I connect a router or a box, the card does not start.
I also tried to change the network speed, I sniffed the network to see if any information was passed at startup but nothing happens.
No power supply.
It says "LanGuard" on the RJ45 connector of the motherboard, it's possible that it has something to do with it but I don't really understand.
If I plug my network into a USB-R45J adapter, there is no boot problem.
Has anyone had this problem or have any ideas?
Thanks in advance.
