Now let me start off saying that my Xbox 360 has been working fine throughout the years. I do have rare freezes on some games. My dashboard has never froze on me before. I have the slim model and I upgraded my hard drive from 250GB to 320GB. Now I tried solutions such as clearing cache, deleting profile and then reinstalling it on both hard drives, resetted my modem, test out wired and wireless connection, and deleting marketplace data. It only freezes in the game marketplace when browsing fast under games, demos, addons and extras while the ads are loading. Im pretty sure it has to be those ads messing with my connection. By the way it started on May 9th while I was downloading the Minecraft trial arcade game. Is this happening to anyone else?
