[SOLVED] I am losing my mind

[Haaaaamster]

Hey, so a little bit of backstory for you to understand my frustration with this situation

Built a PC for my gf at my place everything works fine bla bla bla then one day BOOM the integrated ethernet thingy doesn't work and doesn't appear on the BIOS tried literally EVERYTHING and got an external card that i plugged in, worked for a bit then it kept disconnecting whenever we were playing games, again tried literally EVERYTHING nothing work and it kept disconnecting over and over and OVER

So where are we at now, i bought another motherboard which is the aorus b450 pro version, drivers that came on the CD are installed, tried different ethernet drivers NOTHING works and it keeps disconnecting from time to time which is simply impossible for me only to solve no matter how hard i try

Here's the ipconfig /all if you can take out something from it i'm desesperate, i'm sorry it's in french hope you understand enough

Sorry for the late answer i did check and ddn't find anything interesting but it should be modec laboxv3b sagcm, made by sagecom for SFR

So that's not just a router and modem, but also a 4k dvr for television service.

I agree with you, but it spawned literally out of nowhere and i'm not affected and i use windows too same version same motherboard

So one windows computer got corrupted and the other did not. Get a boot unix device [cd/thumb drive, google can find it easily and it takes 30 minutes]. He is right the chances of 2 pieces of hardware having the exact same hardware flaw is like winning the lottery. It happens, but not to me.
