applied optional BIOS update. stuck in a boot loop

[butterflymanda]

I installed an optional BIOS update and my PC is stuck in a boot loop at the screen that shows that the BIOS update failed unable to read bios (paraphrasing) with the ok button. I can use the pointer. I held down windows logo plus V and windows logo plus V and plressed repeatedly. I was able to get the beeps sequence once but it did not appear to fix the bootloop. then I tried to get to a boot menu, possibly with F9 and I got a spinny circle and got to desktop. it said it needed  to update and restart, so (thinking it had corredted itself [the beeps took place with no display]) I rebooted the PC back into the boot loop, and I cant figure out how I bypassed the BIOS update error white and blue screen to bypass it and get to the desktop, But i know it was possible once. The bios exe on the driver page throws an error, but it doesnt matter if I cant get to a boot screen. So a Optional BIOS update I elected to perform apparently did not perform properly and now I cannot access my PC. I tried removing the GPU. I removed the battery, I helf down the power button with the cord removed. I have been to every support forum page. I dont need to pay a computer repair man to tell me I have to pay to have a new motherboard installed, since i am not risking thermal paste ets on my own. If anybody can point me in the right direction, I would be grateful and thankful

Unless the hard drive has been replaced, there is a copy of the last working bios.

Read section 3 first part

There is also a video

If the disk was replaced or the bios cannot be found then read the second section of the top URL.  You will need to download the correct bios for your system.   Unfortunately, there are 3 possible bios (3 different ones)

If you provide your product ID possible I can tell which of the 3 are correct (if any are)

Alternately, look in the motherboard for a 4 digit SSID code 

Put the bios on a USB as explained and do the WIN + B key again.
