Xbox one power isue

Hello everyone. There is something strange happening with my xbox one 500gb. It starts normally and ask for update. I start the update and after restart he will not power up itself. If I push the start button works for about 10 seconds and shuts down. After 10 minutes starts normally, but also with the update. I have cleaned the inside for dust, i have changed the thermal paste and also the HDD. None of this worked. Any suggestions please. Thank you
