I recently increased my CPU's clock speed using the Ryzen Master software, but my PC won't power on anymore. I tried enabling Game Mode in Ryzen Master and restarted the computer to apply the changes. Now, no matter how I press the power button, the system just lights up and shuts off instantly, along with the fans stopping as well. I only changed settings in the software and not the BIOS. Can someone assist me?

Open the BIOS and return to the standard configuration. If this fails, remove the CMOS battery, and follow the instructions in your motherboard manual.

To access the bios when the pc won't turn on, try using the boot menu by pressing the appropriate key during startup. This will open the system settings and allow you to enter the bios.

And if you don’t have the manual, is there an online way to get it?

If accessing the BIOS is impossible, proceed by erasing the CMOS. You may still manage to enter the BIOS.

From the motherboard manufacturers' website, you can find a dedicated page for your specific model. This page contains the manual, drivers, and BIOS versions. Make sure the BIOS and drivers are current.

I attempted to remove the battery for 30 seconds and it didn't work either. I tried using the jumper method, but the LED lights in front of the PC kept cycling and then shut off completely without any display showing anything.

It’s an HP system, but the manual doesn’t explain this feature as clearly as it does for a standard motherboard. I discovered it in the provided link. On page 10, there’s a mention of a Password Jumper; the image shows that the jumper beneath is labeled CMOS. When the computer is off, place the jumper on these two pins for ten seconds, then return it to its original position. After that, power up the PC again. If this doesn’t resolve the issue, you might need to remove the battery (#21) and attempt to clear CMOS once more.

I notice the 6 pins but it doesn't specify whether it's CMOS or SW_CMOS, it just says FDO.
