I'm using a gigabyte z490m which I have somehow messed up the bios and the pc is now unbootable. I tried anything, starting up without certain ram sticks, removing the gpu, resetting the bios using the cmos battery removal method but still no luck. I suppose that it must be a total bios failure so I'm asking if I'm able to somehow change my bios chip or where can I buy a new one if it's possible
