Question Fail boot after update bios

[Darker Knight]

I downloaded a custom BIOS on my old computer. It worked normally but I went into the custom BIOS settings and activated some new options added in the custom BIOS and when I did that I tried to turn on the computer but it showed me a black screen with no response when F2 I don't see any sound in general everything doesn't work I tried removing the battery I left it for 30 seconds but it still didn't work. Is there an actual solution for a dead computer due to the BIOS?

My module Laptop : Acer Extensa 5235

Well, why is it a "custom" bios; what's different compared to an official bios; and what settings did you change? I would suggest first trying to boot without making any "custom" changes to see if it boots using the default settings.
