Constant sign in & out

So that only half answers my question then...I will keep that in mind however.

Make sure the power supply is not covered up, and put it on an upside-down egg carton, or other elevated surface which lets it stand above the floor and therefore cool faster. If that does not work, you may need to replace the
power supply.

Qamun,

If you have no problems signing into Xbox Live and 100% without a doubt know your e-mail and password associated with your Microsoft account, try safely deleting your profile, clearing your system cache 3 times, restarting your console, then re-downloading
your profile. Just follow these detailed steps:



Sign out of your Gamer Tag Profile:

1) Press the Xbox Guide button in the middle of your Xbox controller and Press the Blue X to
Sign Out



Delete Profile:

1) Press the Xbox Guide button in the middle of your Xbox controller

2) Scroll right and go to the Settings tab, and then select System Settings

3) Select Storage

4) Select the device with your profile

5) Select Profiles

6) Select your Gamer Tag

7) Select Delete

8) Select Delete Profile Only



Clear System Cache:

1) Scroll right and go to the Settings tab, and then select System Settings

2) Select Hard Drive

3) Highlight Hard Drive, and press Y (Device Options)

4) Select Clear System Cache and select Yes

5) Repeat steps 2 thru 4 two more times so that your Cache is cleared 3 times

*NOTE* The cache stores such items as game updates, system update installation packages, and gamer pictures of your friends. Clearing the Xbox 360 cache does not remove your Gamertag, content that you have downloaded, game files,
or console software updates.



Turn off your console and start it back up.

Download Profile:

1) Press the Xbox Guide button in the middle of your Xbox 360 controller

2) On the Home tab, select Download Profile

Is that a solution to stop the sign out problem?

I'm thinking about restarting my router but my brother is playing his xbox.....

That took care of the problem. Thanks!
