If anyone can help me on this issue I will appciate it a lot. Ok here it is. I have had my xbox for about 4 - 5 yrs now. I have the new powercord that was sent out. my xbox is modded. Now this is what is happening. My power button doesnt work, when I plug in my xbox it turns on on its own. I have to unplug it to turn it off. I can play for about 10-15 mins then it shuts off on its own. I have taken it apart and found no broken traces on the power supply or bad solder joints. 5 blew out some dust with a can of air. I still have the same problem. Help me if you can.
