I have a MSI z87-G45 MOBO running 1.50 BIOS version. The latest problem I'm having, that I can't seem to figure out is everytime my computer turns on, whether restarting or turning on from a shut down, the wired adapter stops working and in the device manager it says it cannot load the drivers for this hardware. My temporary, very annoying, fix for this is to have the windows 8.1 drivers for the killer network on a USB and install those everytime I need to. I read somewhere that they fixed this on a BIOS update, but I've has also read its really difficult to flash a BIOS and I get nervous whenever I do stuff like that. What do you guys think??
