So, i just built a new PC. 16GB Ram, i3 10105 and Gigabyte H410M H V3 Mobo... The first time i booted windows and plugged in the ethernet cable, i got no internet connection. Tried to install some drivers via usb from another pc but all realtek driver installers tell me that my Network Card is not found and maybe is in deep sleep mode. I tried unplugging the RAM from the PC cuz some people said it might fix the deep sleep problem but it fixed nothing. Also, the Ethernet Adapter on the Device Manager is appearing under the "Other Devices" category with an exclamation mark. Im starting to believe that the network card os broken and the motherboard needs replacement. Any help would be greatly appreciated
