My PC was working perfectly last night, but when I turned it on today it went straight into the UEFI BIOS settings. Nothing was moved, unplugged, or changed inside the computer. I've tried researching fixes for the past couple of hours, but I still can't get it to boot normally. What should I check first?

A full power reset is worth trying: shut the PC down, unplug it, hold the power button for about 30 seconds, reconnect the power, and turn it back on. That can clear an occasional firmware or power-state glitch.
Try saving and exiting the BIOS rather than just restarting. If the computer keeps returning to BIOS, the boot drive may be missing or its boot files could be damaged. A drive that still appears in BIOS may be repairable, while one that isn’t detected points more toward a connection problem or drive failure.
This could be a failing boot drive. Check that the BIOS detects your storage, memory, and other hardware correctly, then verify the boot order. If you have a bootable operating-system USB or another drive, testing that can help determine whether the problem is the drive or the rest of the system.
First, check whether your storage drive appears in the BIOS. If it’s listed, make sure it’s selected as the first boot device, then try saving and exiting with F10. You can also restore the default BIOS settings and reboot. A weak motherboard battery can sometimes reset the settings and cause this.
Some systems reset to safe BIOS settings after a power fluctuation or failed startup. Recheck settings such as the boot mode and primary boot drive, save them, and restart. If the settings keep resetting, the CMOS battery may need replacement.
If the drive isn’t listed, power the PC down and reseat it. For an NVMe drive, remove it and reinstall it firmly; for a SATA drive, check both the data and power cables.
