Xbox 360 Slim Power

Hello, so one day I came home from school and my Xbox 360 Slim turns on but like 0.5 seconds later it turns back off and the power brick turns red. Before I turn it on the power brick is yellow. I tried everything to fix but nothing works. So, I ordered
a new power brick and when I plug it in to my Xbox it turns on for like 3 seconds and turns right back off but the light is orange when it turns off. Help! Is there something wrong with my Xbox 360 Slim instead?
