How Do I Fix the Graphical Display Problems on My Xbox 360?

So here's how it started: I turn on my xbox and three red rings blink on the power button. Frightened, I unplug the power supply and take the xbox out and blow on it and whatever. So when I plug it back in and turn it on it works fine. But i started to notice when i play any games, the red turns into green on any game, and at loud points in the game, green lines will go through the screen… I know its really weird. Whats wrong with my xbox? Please help!!!

Suggestion:

It's actually not that weird. You'll probably get some advice to try to fix it yourself but your chances of success are next to none at best. If it's still under warranty, bit the bullet and send it in to Microsoft. If it's not, check on what it would cost to replace the board. The best option, though, might be to find a good used Arcade version at GameStop or other outlet and keep your hard drive and then use it on the new one. You should be able to do this for under $100.

Your problem is most likely a heat issue and/or actual board damage. There's no simple fix for it.
