Question LEDs on motherboard turn on and PC boots but this never happened before

[sulfpanda18]

I installed new ram which turned out to be defective and I returned it but after I reinstalled my old ram my LEDs on my motherboard now light up which never happened before. Is this anything to worry about? Will this cause any problems in the future?

what LEDs exactly?

aesthetic RGB,
error lights,
error codes,..?

you may need to verify with the board manufacturer if you do not know what any corresponding error lights or codes represent.
the manual should include this information but you may need to look elsewhere if you're not sure what they are.

include your complete system specs with make & model of all components.

According to my manual if the light is on is means it failing to detect that part and the VGA led, Boot led, and CPU all turn on before booting up.

My specs are
ASUS Strix 3060
MSI B550-A Pro
Ryzen 5 5600x
Oloy 16gb 3000 mhz
Inland 512gb SSD
