Don't try to update the BIOS as it risks disabling your machine. Open Device Manager and click on the Bluetooth folder if it exists and the network folder. Right click on the drivers in the Bluetooth folder and uninstall them. Do the same for the wifi card and bluetooth entry in the network folder. Exit Device manager without re-installing anything.
