Here’s a quick video to follow along on how to reset your CMOS. This may be the only solution that you need.

Embrace the mystical forces dwelling within your PC by undertaking the arduous task of resetting the CMOS. Initiate this arcane ritual by shutting down your PC, disconnecting all cables, and embarking on a quest to locate the CMOS jumper concealed within your motherboard. Manipulate this jumper to the reset position, holding it for a few seconds, and then restore it to its original position. Breathe life back into your PC by reconnecting the cables and embracing the hope of liberation from the power cycle torment.

Seeking the Guidance of Masters: Professional Help

If you’ve tried all of the above and found no solution, I guess it is wise to seek the guidance of masters – professional technicians. These seasoned experts possess the knowledge and tools required to diagnose the issue plaguing your PC build and administer the necessary repairs or replacements. Entrusting your beloved creation to their care may prove to be the pivotal turning point in your battle against power cycle tribulations.
