When i take my game out of my 360 the games always warm

Because it is an older game, the online servers may no longer be active for this game. Go to Rockstar forum to see if this game server is still active.

Xbox 360 games become warm if your 360 is not in an area that is well-ventilated. The 360 pauses because it is beginning to overheat. If your system did not pause, but instead kept running until it shut down, you might get the Red Ring of Death.

The newest version of the 360 automatically turns off when it is close to overheating. The older version just pauses because it is losing its ability to function normally.

Move your system into a more open-aired area!

try soaking the Disk in warm soapy water and try it off with a clean towl , if not try checking your xbox settings. If it donsn't work your Halo 3 game is stuffed , try buying a new one (Halo is aweasome :)

Can you connect to XBOX Live to get firmware updates??
I assume you always update when the game gives you the oppurtunity, these updates include playability issues, glitches, etc.

I have this router and have just enabled the NAT settings from Strict to Open:-

1. Log into router's IP address (192.168.1.1) and enter password. Select "Advanced Setup".

2. Click on Advanced on left hand menu and select UPnP

3. Check all three boxes in window and click on Apply

4. Close router configuration window and run XBox test again. Worked for me!

Even though you can't see scratches on your game disc, it's still scratched. Do what I did. Go to sellitbroken.com and sell your game to them. They will give you good money for it.

how do i fix the 3 red rings of death?? please tell me i relly want to start playing again

1. Select memory -> Select Y button for device options then press the following sequence on your controller

X,X Left Bumper, Right Bumper, X,X

You will see a message that goes like this " This will perform maintenance on your xbox 360 storage device, would you like to continue? Select Yes

2. Try if the game will load faster.. We just need to refresh your system..

is the light flashing red and orange?

This problem may occur when the Xbox console is too hot or is overheating. The flashing lights mean that the internal temperature of your Xbox 360 console has exceeded acceptable temperature limits. Let your Xbox 360 console cool. You may have to wait several hours for your Xbox 360 console to cool enough. Don't turn on your Xbox 360 console when the console is hot.Verify that your Xbox 360 console has enough ventilation and that the fans are operating. If the two lights continue to flash red after you try steps 1 and 2, contact Xbox Customer Support.

Microsoft can be contacted by finding the number listed on the back of your video game booklets.

Good Luck to you and Happy Gaming.
