I noticed that whenever I mean. Xbox turn off the Xbox symbol for approx. 10-15 seconds and then the console is really off. In addition, my Xbox has also become a lot louder… It is now almost 3 years old. I didn't have a download or run like that so it really can't be. The whole thing has only been going on for a few weeks and I have also noticed a few strange things about technical devices that go in the direction. Therefore I wonder if there's any program running in the background like a virus that was infiltrated via the WLAN because the other devices also had something noticeable…
The louder will probably be the fans, there will be a lot of dirt in there and the bearings of the rotors will get some play. You could open it and gently hold a vacuum cleaner inside. The cooling fins should be free again.
maybe when she shuts down she sorts her database, which has certainly not shrunk. They don't have to be viruses.
Reset the XBOX to factory settings. Then there should be rest.

PS. It certainly can't hurt to have the box opened by a specialist and cleaned from the inside.
OK thanks!
