I just experienced a power outage, and now my PC won't display anything when it starts up—though the Caps Lock light works. After some tinkering, I switched the HDMI cable to the motherboard, which allowed me to access the BIOS. However, it then says it's "preparing automatic repair" and "diagnosing". But eventually, it tells me that automatic repair couldn't fix my PC, giving me the option to either shut down or go to advanced options that aren't really helpful. I'm using a Windows 10 desktop. Does anyone know how I can resolve this issue? I couldn't find much useful information online.

Don’t forget to check if your primary hard disk is set to AHCI mode or normal mode. Switching these modes could make a difference. If that doesn't help, verify what your current mode is, then head to the repair options screen and look for a restore point to revert back to a state before the outage—it might just do the trick!
First off, try resetting your BIOS settings to default—that's often a good starting point. Just save the changes and see if you can boot normally. If that doesn't work, make sure Secure Boot and TPM are enabled in the BIOS. After that, if you're feeling adventurous, try pressing F8 during boot to revert to a previously working recovery state. Depending on your hardware—a hard drive (HDD) or solid-state drive (SSD)—if it's an HDD, there could be physical issues, like a damaged needle. In the worst-case scenario, you might consider using a bootable USB with Windows 10 to recover your installation.
