I changed several BIOS settings while trying to improve my PC's performance. After that, the SSD stopped appearing in the BIOS, and the computer could no longer boot into Windows 11. I then changed more boot or storage settings while trying to fix the problem. Now the computer stops at the ASUS startup screen, which says "Press Delete to enter BIOS," but pressing Delete or F2 has no effect. I'm unable to reach the BIOS or Windows and don't know which setting caused the issue. My system has a B650E Max Gaming WiFi motherboard, Ryzen 7 7800X3D processor, Kingston RAM, a Kingston SSD, and an RTX 5070. What is the safest way to reset the BIOS or get back into its settings?

Start by clearing the CMOS. Shut the PC down completely, switch off and unplug the power supply, then use a screwdriver or another metal object to short the motherboard’s two CLRTC pins for about 5–10 seconds. Reconnect power and try starting it again. This should restore the default BIOS settings.
If the reset procedure had no effect, repeat it with the power supply unplugged and make sure the CMOS battery is removed for several minutes if your motherboard manual allows it. Then reconnect only the essentials: CPU, one RAM module, graphics output, keyboard, and motherboard power. If it still freezes on the splash screen, check the board’s diagnostic LEDs and consult the motherboard manual, because the problem may be hardware detection rather than just a boot setting.
If clearing the CMOS doesn’t work, power the system off and disconnect every storage device, including the M.2 SSD and any SATA drives. Leaving the motherboard without a boot drive can sometimes force it to open the BIOS. Also try a basic wired USB keyboard connected directly to a rear motherboard USB port, since some front-panel or wireless keyboards may not be recognized early enough during startup.
I tried clearing the CMOS, but the computer still stops at the same ASUS screen and I still can’t enter BIOS.
