Question

My Coby Mp3 model MP-C7095(2GB) turns on but it doesn't enter in the mainmenu. It only Shows "Coby" and then it gets stuck it won't even turnoff. I've tried connecting it to my computer and when I do that, the screenturns white and then it gets stuck again. I just got this Mp3 , it has only 2weeks and already it has problems . How can I resolve this? Please help me!
