I tried to flash my gigabyte a320 hd2 motherboard with the f4 bios update and the update was disturbed by a power cut midway and I have a bios failure.My display is not responding to my gpu,usbs are dead and I tried putting in my motherboard disc but it is not responding the screen just stays blank with the no display message.I opened my cabinet and all parts seemed to working all fans where spinning and the lights on the motherboard where on.I was using the flash option from appcenter and the power cut occured during the reboot after flashing was complete.How do I fix this?Thanks for your help guys.
