I'm facing a frustrating issue after enabling Secure Boot on my Gigabyte motherboard. My computer isn't compatible with the Windows 11 upgrade, so I decided to access the BIOS to enable TPM and Secure Boot, but now my display isn't working. I have an AOC monitor that shows 'no input' before going dark, and I need to see something to revert the changes I made in the BIOS.
Here's what I've already tried:
- Unplugging the GPU and SATA cables, just leaving the power supply connected.
- Swapping out the HDMI cable and trying to connect directly to the motherboard using the HDMI port (ensured the monitor was set to HDMI mode).
- Utilizing my drawing tablet as a makeshift monitor.
- Removing the motherboard battery and discharging it a few times.
- Following a YouTube guide, but I can't seem to find the Q-Flash feature on my board.
- Moving my RAM sticks to different slots.
My specs include a Gigabyte B460M DS3H AC motherboard (Version 1.0), an Intel i5-10400F CPU, 16GB of Corsair RAM, a GeForce GTX 1050 GPU, and SSD and HDD storage. The BIOS is set to Legacy mode, which seems to be part of the problem since Secure Boot doesn't work in this mode. Ideally, I want to play games without having to upgrade my motherboard, but I may need to if I can't resolve this. I'm a bit of a beginner with PC building, so any guidance with basic terms would be greatly appreciated!

Don't get discouraged! The display issue might just be related to the Legacy mode. Once you've cleared the CMOS, check if the BIOS can switch to UEFI if your drive is GPT. If you're still stuck, let us know what you see after resetting!
It sounds like the Legacy BIOS mode might be causing issues with Secure Boot. Make sure your hard drive is formatted as GPT instead of MBR for Secure Boot to work. But before anything, clearing the CMOS is definitely a good first step. Turn off your PC and follow the instructions to reset those settings.
First things first, try clearing the CMOS on your motherboard. This usually resets any changes you've made and might restore your display functionality. You should find instructions in your manual, or you can typically use a screwdriver to short the two small pins labeled for clearing CMOS.
