earlier today i turned on my computer and it activated a forced BIOS update, nothing seemed out of the ordinary. then, once the update was over, I botted my computer up. it now cannot connect to the internet, shows that I have no possible connections, and will not let me access connectivity settings. trouble shooting did nothing, and, truth be told, I'm at a total loss
 
it uhhh, flashed...? like, it flashed a command screen for a split second, and then disappeared. it looked like there might have been text on it, but it didnt last long enough to see
