Have you tried to get into the bios? Have you tried to flash the bios back, read the manual on doing this. Have you tried to reflash the bios to the updated one you were doing?

Which BIOS update method (i.e. Instant Flash or DOS or Windows) were you using?

What's more important is, why did the PC turn off during the flash?

Did you have a power grid failure or lightning storm while the flash was occurring? Did someone trip over the AC power cord?

What BIOS version were you updating from and to?

I was updating to 2.0 from 1.8. Someone tripped over the pc power cable. There is no signal to the tv so I couldn't reflash ( I used windows flash method) on the debug led it says d0 if that helps.

Look up what the error code is in your manual.

Since the flash is incomplete you have a corrupted UEFI BIOS.

There's no way to boot with a corrupted BIOS.

The SPI Flash Memory chip will need to be reflashed by someone with an SPI Flash EEPROM Programmer. Usually that requires sending the motherboard back to ASRock. If you know someone who has an SPI Flash EEPROM Programmer you can get them to flash the required BIOS image to overwrite the currently corrupted image.

No it's not covered under warranty because it is considered user error and not a manufacturing defect. It was working fine when it left the factory.

Motherboard manufacturers have always had a disclaimer regarding BIOS flashing. It is always flash at your own risk.

If the SPI Flash EEPROM chip on your motherboard is socketed and not soldered to the motherboard and you know someone with the same motherboard and they will allow you to do a BIOS hot flash that is another way to recover.

To ASRock? Only if you get prior approval from ASRock that you can send it to them to have it reflashed for a fee and you will have to pay all shipping costs both ways.

The charges, that I've read about, usually add up to nearly the cost of a new motherboard. Only you can decide if that is worth it to you.

Edit: After looking at a picture of that motherboard it looks like the BIOS chip is socketed so you can just order a replacement chip with the latest BIOS version already flashed to it.

Thank you so much. Do I need a special too to remove the chip or just by hand is ok

It needs to be pulled straight out. Tilting it, too much, will bend the pins.

You can use a precision screw driver to slightly pry up one end (i.e. the narrow ends without any pins on them) and then the other and keep alternating until you've loosened it enough so that you're able to grab it with your fingers or a pair of needle nose pliers to pull it the rest of the way out.

Inserting the new one must also be done correctly keeping in mind that the chip pins are numbered and must be inserted with pin 1 of the chip matching pin 1 of the socket.
