I recently borrowed three games( Battlefield: Bad Company, Ninja gaiden 2, and enemy territory: Quake Wars) from my friend and have been playing them from a day or two now. Today, however, while playing Call of Duty 4 online, very thin vertical black lines suddenly sprang onto my screen. At first I thought it might have been the TV or some small malfunctioning device, so I unplugged everything and played again. Again it happened, and I tested all my games and it does it ith everyone. Some games have color distortion as well. This problem doesn't seem to happen on teh dashboard or with arcade games. Also, if this little knonwledge will help in explaining or helping me with my problem; I have the xbox 360 elite with 120 G harddrive and I got it brand new from the store around January of '07. I have a best buy warranty, but i would rather not go through that hassle. I tihnk it might have been triggered by one of the new games put into the machine and all 3 required a update. What is wrong I don't use Hi-def settings or TV and I checked all the cables and discs. It doesn't seem to be any of them. It must be something internal.
