My laptop model is Acer Nitro ANV15-51. RTX 4060 75 Watt, i7 13620H, 16 GB 5200MHz DDR5 RAM, 512GB SSD, 165Hz 3ms monitor Windows 11 Home Single Language.

BIOS Version/Date INSYDE Corp. V1.26, 03/21/2025
SMBIOS Version 3.4

About 1 month ago Windows Update updated the BIOS. After this update, while playing games, the GPU usage that was normally 100% and stable FPS started to drop FPS due to constantly fluctuating GPU usage. The GPU suddenly drops from 90% to 60% and then goes up to 80% etc. It never stays stable and that's why, for example, the game I normally play at 180 FPS is now playing at 100 FPS or below and freezing occurs. When I try to download BIOS from the official website of the product and install the BIOS, I get the error "this bios file is not allow to flash. the flash process will be terminated". That's why I can't update the BIOS. There are no other changes on the computer, the source of the problem is definitely the BIOS update because I started having this problem right after this update.
