Hello, my X360 Slim 250GB freezes while playing games such as Gears of War 2, Homefront Multiplayer demo, Black Ops and others. I am using a Wireless Connection and i have tried all the steps that were suggested in the "Screen Freeze Wizard" such as taking out my hard drive, changing my Xbox's place and others. I have a feeling that WiFi is causing the problem, but i was using a Playstation 3 with the same router and i didn't have similar problems, also my ISP is really good...ahh.. I don't know what i should say any more.. Maybe anyone had similar issues and knows how to resolve the problem?.. Also it happens pretty inconstistently, My XBOX360 can freeze ~2 minutes into gameplay or i can play for more than one hour without freezes... very strange.
