I keep getting three red rings in the part where it shows how may controllers are playing and i can't get any of my games to play or my controllers to work

Three lights flash red on the Ring of Light (RoL) on the front of your Xbox 360 console. The upper-right quadrant light is the only light that does not flash red. The three flashing red lights may indicate that there is a hardware problem with your Xbox 360 console.

You can try one or two things.

1. Turn on your xbox and check to see if the power supply light is green. If it is green there is a problem with the system. If it is red it means you should check your connections and restart the xbox.

2. These rings have a tendency of meaning that there is a problem with the system itself. Most companies sell extra insurance to cover this "ROL" Ring of life. You can contact Microsoft by calling them. The number is usually listed on the back of the video game booklets.

I wish you the best and I hope this resolved your problem

Happy Gaming
