In-game graphic breakdown

Its likely that your graphics card doesnt support it, or it is struggling. You should try to lower your graphic settings from within the game. If it still flashes, you should try getting a new graphics card with at least 512MB of memory. A Nvidia 8800GT would suffice.

u have a melted graphics chip send to microsoft n tellem u have the 3 rings and theyll fix it

Halo 3 is buggy disk , I have 2 brand new copys of halo 3 for testing repaired drives
and found that of all the 360 I repair, benq drives will read 99% of the time the hitachi
seem too slow on the seek time to get a
lock/read resulting in a dirty disk error.

Halo 3 does not play on all 360
its just a picky disk .There seem to
be two xboxs thoes that will load halo 3
and thoes that will not.

Sorry this may not be very helpful

Try using a DVD/CD lens cleaner (found at walmart/best buy).

The games are read by the lens, and processed through the internal graphics system. But the Dashboard ( and possibly the guide too) don't have to go through the lens.

If the cleaner doesn't make a difference try this-

Start your 360 with Halo 3 in the tray.
On the XBOX Dashboard, scroll to the section where you would press "A" to launch the game, but instead press "Y".
If your 360 is up to date, you should have the option to save the game to your hard-drive. -Do it
Hopefully, it will download without the static issue.

If that doesn't work, contact Microsoft.

sounds like the graphics chip is on its way out might just be a cold solder joint normaly turns to 3 red lights when ppl mention this to me

You have an incompatible graphics chipset.

you can try installing the game onto your hard drive and then playing it, or try to get a new copy of the game. the xbox number is 1-800-4MY-XBOX

the only way i know to clear the hdd is to do it manualy from the dashboard.

three red lights in my xbox 360

when the new games came out, the console updates itself when you go to play the game. Look on the back of your console at the numbers. (not serial or part) You should see 2006 or 2007. It is most likely that you have an 2006 which means that your graphics card isnt strong enough to handle the graphics from these games. If you call up microsoft and tell them that the console had the 3 red rings (even though it doesnt) They will take your console, repair it, and update it all for free.

I think this is less of an isolated issue but a universal one. As Halo 2 (and I'm assuming the version of Medal of Honour you speak of) are original xbox games, these can be prone to graphics distortion due to being emulated. I often find my Halo 2 campaign mode sometimes "ghosts" or leaves certain outlines stuck on the screen, which is irritating but nothing too major. If this happens in any designated xbox 360 game, search the web for similar problems with the game itself, if not give Microsoft a call. Bring food, it's a long call wait :)
