Yesterday I tried to update the BIOS of my Asus a7v8x-la (Award-Phoenix bios) based motherboard with a custom BIOS build.
But the operation was interrupted in the middle, and the PC is now stuck at the bios screen.
I am unable to press the F2 to enter BIOS setup or Del to enter the boot menu.
Nothing happens when I press any key. I waited around 4-5 minutes, but still, it is stuck. No LEDs in keyboard are also blinking.
Could anyone tell me a solution to fix the issue?

Thanks in advance

    I think you've turned your motherboard into what's commonly known as "a brick" - should never interrupt a bios / firmware update – Xen2050 Sep 29 '18 at 5:11
  • Thanks for the reply. How can I recover from this? – Harikrishnan Sep 29 '18 at 5:33

    If it will still try to boot from something (usb/hd/drive) you might be in luck... I've read that routers that have been bricked can sometimes be recovered using something like a jtag connector, not at all sure about motherboards. They used to have bios stuff on a specific chip, sometimes they were swap-able or solder on a new one... If you can exchange it under warranty that's best (if they allow "bios update failure") – Xen2050 Sep 29 '18 at 5:38
  • Oh ok. I will check for bootable option. – Harikrishnan Sep 29 '18 at 5:41

You could try to reset the bios by removing the CMOS battery.

If this doesn't work, you would need to short out the BIOS and force it to use a backup BIOS which may be available on the BIOS chip. But this operation is better be done by a qualified repairman.

Under extreme conditions, the BIOS chip itself may be exchanged for one that contains a compatible version, which is better better done through your supplier or the manufacturer.

  • Thanks for the reply. What do you mean by " short out the BIOS"? how can I do that? – Harikrishnan Oct 1 '18 at 4:34
  • I'm not a repair-man - all I know that you short together two pins on the BIOS chip, but I don't have any details. – harrymc Oct 1 '18 at 7:54
