Clear CMOS
The CMOS (Complementary Metal-Oxide-Semiconductor) stores the BIOS settings of your computer. Resetting the CMOS can sometimes resolve booting issues related to incorrect or corrupted settings. Users on the LevelOne tech forum mentioned that they resolved this error using this step, doing so also helped us. Here is how to clear CMOS:

Final Words
The issue of the PC not booting but fans spinning may get annoying to many users, but is very easy to fix. When on Twitter I came across threads of people mentioning that they don’t even get as far as the BIOs screen when facing the issue.
Hmm, my PC won't boot. Fans spin but it doesn't even get as far as the BIOS screen.

One user stated that they could force start their PC with a button on the motherboard and asked if it was safe. We would not recommend doing so as it may damage internal components.
PC won't boot. Fans spin for a second then it restarts. But i can force it to boot with a button on the motherboard. Is it safe to do this?
