Hello Creepie Boiii, Welcome to the Microsoft Community!
According to your feedback, you are experiencing startup issues with your Win10 computer
According to your description, this is your computer detecting hardware after booting up.
The underlying logic of the lights on this computer that are running is designed by the computer brand manufacturer
The color and indication of each light may indicate a problem with some part of your computer.
Therefore, you can report your problem to the brand of your computer.
If you are using a desktop computer, you can contact the motherboard manufacturer.
Thank you for your understanding and support.
I hope you find this information helpful.
