Last night was fine.,The machine can't be accessed when I get up in the morning.,So I forcibly restarted it.,And then it can't start.,It can't start in recovery mode.,It's stuck in this interface.,I look like a network card problem? But if there is a problem with the network card, will the system not be able to enter? This machine has been working normally for more than 2 years and has been doing well. Can someone help take a look? Thank you
