I downloaded the latest BIOS update onto a USB for my ACER Predator PO3-640. The issue is that I didn’t remove one of the files/folders (Appendix folder) that contained a PDF file when I updated to the latest BIOS version. After doing so and starting to play, my game crashed, and I got a warning message where I essentially had to shut down the computer. When I did that, I couldn’t access the computer/Windows anymore. I’m prompted to choose a language, and after that, I have six options, including something related to UEFI, default recovery, quality recovery, and some other options, but I can’t perform any type of recovery because they all fail.
I formatted the USB stick and tried downloading an older BIOS version onto it, this time removing the PDF files—so I believe I did it correctly. However, when I updated to an older BIOS version and the computer started, I received an error message that said: "Setup settings error, CMOS checksum error, or CMOS battery loss occurs. Default settings loaded." I also got this error message the first time I updated the BIOS, but back then, I was able to log in and play. Now I can’t access the computer at all.
I have tried to remove the CMOS battery and wait for a while and then plug it in but still the same issue, I tried to install windows tool onto the USB but it seem not to be able to find it/recognize it in the BIOS so it didn't work either. I really don't know what to do and is my motherboard maybe cooked, please help.
