"Something went wrong" when turning on the Xbox Error: 0x800401fb

I get the same message ' something went wrong use code 0x800401fb at xbox.com\errorhelp', and
when I type it into the error search it says it doesn't exist. Could really do with some help here please.

try clearing the cache of the console by holding down the power button on your console for 10 seconds.

Edit: now when I turn the console on - Something went wrong restart this Xbox box troubleshoot system error E200 000000074 00000000

I'm having this same issue. I started up the Xbox like normal. I bought it a year ago this month and have only used it 6 times for Christ's sake. So I start it up and everything works fine. I go to play for a motor sport 6 for the
first time and I get to the title screen and press a and it gives me a something went wrong error. Well I quit the game and now every single thing in the home menu gives an error when you click on it. So I restart and now I can't sign back in. Same error 0x800401fb
over and over. Still have downloads going, and later on one of them finishes and the system **** off from inactive and I restated it and was able to sign in to my profile. Then I got Diablo 3 on the hard drive to start and played for an hour, thought it was
fixed, then I went to the menu and tried another game and nothing works, not even settings, same error message. I just shut it off again and right away went to battlefield one and it's working. But again, anything else is all something went wrong and error
0x800401fb

Ive tried every style of reset i can think of and read about.
