I was attempting to increase my CPU's clock speed, but it went into a boot loop and then restarted. After rebooting, it failed to display any output. I've reset the CMOS using both a jumper and removing the battery, but setting the BIOS back to defaults hasn't resolved the issue.

Full process described. If this does not function, it indicates a serious issue, though unlikely unless you were making extreme adjustments. Adhere strictly to each step without omission. Carry out all instructions precisely as they are given.

BIOS Hard Reset steps
Turn off the device, disconnect the power supply and detach the PSU cable from the wall or supply unit.
Take out the CMOS battery on the motherboard for five minutes. In certain scenarios, you might need to remove the graphics card to reach the CMOS battery.
While waiting, press the power button on the case for thirty seconds. Once the five minutes have passed, reinsert the CMOS battery, ensuring it is oriented correctly as it was removed.
If you had to remove the graphics card, you can now reinstall it, but make sure to reconnect any power cables and your display cable as well.
Reattach the power supply cable, turn the PSU back on, and restart the system. The display should show the POST screen with options to configure CMOS/BIOS settings. Launch the BIOS setup, adjust boot parameters for Windows or legacy systems, and if needed, set drive-specific configurations.
Save your changes and exit. If the system successfully enters the POST and boots, proceed further—this includes returning to the BIOS and setting up additional custom configurations such as memory profiles, fan settings, or other parameters that may have been lost during the reset.
In certain situations, after resetting, it might be necessary to load default or optimal values in the BIOS to restore hardware tables for the boot manager.

It is advisable, especially when performing a hard reset, to switch to a different display type—many devices fail due to displayport settings. Consider using HDMI if you experience no display or visual issues, or lack of signal feedback.
