Xbox One S boot up takes forever

Does it run fine once it's up and running?

Yeah some games take a while to load up to though don't know if there's any relation.

I'm sorry your having problems with your console. Here are some things you can try.

Try clearing your storage device cache:http://support.xbox.com/xbox-360/troubleshoot/hardware/clear-system-cache

Try deleting your profile and downloading a fresh one:

Does your console have a hard drive? If you remove the hard drive, does the dashboard load up quickly now?

I noticed when I had my OG Xbox the other day with Instant On, my dashboard would take forever to boot up. Now that I'm on the S, it doesn't. But that could also be because I have it on energy saver now. Idk

Hello, first it's a pleasure to be able to help you today.

My name is welcome to the community.

Hello Duane, I don't know how long your Xbox One S has been in its way, but depending on how long it may be slow cause of dirt inside it (dust), this consequently compromises the cooling of the console.

If you've tried both types of factory reset, keeping games and Apps and erasing everything, and it's still slow and slow to start and slow to navigate menus, it may need an internal cleanup.
