My PC shut down normally last night, but today it suddenly started showing a black screen during boot. After removing one RAM stick, it boots into Windows normally, but it will not start with both sticks installed. I cleared the CMOS, waited several minutes, and replaced the CMOS battery, but I still cannot enter the BIOS. The reset screen appears once after clearing CMOS, followed by another black screen, and booting into UEFI through Windows Advanced Startup does the same thing. I can use the computer with half of the memory, but I cannot access BIOS or Q-Flash to update the firmware. What should I try next?

Gigabyte’s App Center may provide the @BIOS utility in newer software versions, but flashing firmware from within Windows is risky when the memory configuration is unstable. It would be safer to identify the bad module first, then use the board’s supported Q-Flash method once BIOS access is restored.
Test both memory sticks individually in the recommended A2 slot, then try the other slots if necessary. Running a memory test such as MemTest86+ can help confirm whether a stick is defective. Since one module appears unable to boot by itself, replace or repair the memory before attempting a BIOS flash.
If the system has Ultra Fast Boot enabled, it may skip the normal delay where Delete or another key can open the BIOS. With the working RAM installed, try disabling Fast Startup in Windows and use the motherboard’s UEFI firmware option from Advanced Startup. You can also try a different keyboard or connect it directly to a rear USB port.
