Chosen Solution
So my Xbox One has started a seemingly endless on/off cycle where it plays the start up noise, shows the Xbox green screen makes it to the home page then beeps again and shuts down to start the whole process over, replaced the power supply and the issue continues. Help.
There are many possible reasons for why this is happening. Overheating, a profile bug issue, faulty power supply, faulty power distributor. You can try factory resetting the power supply, remove or change the power surge protector, make sure everything is placed in a well ventilated area, not blocked in a shelf for example. Without more testing, it is hard to find the cause but this might help: http://support.xbox.com/en-US/xbox-one/c…
