My current system is on its last legs, but I believe a mobo swap will solve my issues. I upgraded to a 3070 (EVGS XC3 Ultra) earlier this year. I replaced a 2070 of the same model. When I booted my PC for the first time after the swap, the ethernet port on my mobo did not work. I tried ALL of the drivers troubleshooting, and ended up buying a usbC adapter for ethernet. This worked fine for a few weeks, then the usb C port stopped working. Since then, I have been using a usb 3.0 adapter and I haven't had any issues with ethernet connection since then. In the past few days I have noticed a USB port which my wireless mouse dongle was in has been freezing on me, but the firmware is up to date. Could anyone help me with this issue?
