Please list all your system specs....brand/make/model.

Does the system power up: Do you hear the POST beep? Does windows load?

Did the case come with some sort of RGB lighting node. Usually the fans power 4 pin get plugged into the mobo fan headers. Then the LED cable goes to the node.

What CPU light are you referring to?

There are three different msi performance gaming boards. You need to list the exact motherboard. Use the name from the box. Next have you read the guide at the top of the forum for problem builds? If not, do so. If you follow ALL of the steps, you will find the cause of your problem.
