Okay I had a perfectly working xbox360 phat system. manufacturing date is late (sept) 2009 so its defiantly a keeper. I got mlb 2k12 brand new played it maybe 5 days, then it started freezing at the start up screen. Game says press start, loads all files then freezes. I exchanged the game for a brand new one still did it, got a brand new dvd drive swapped pcbs, played the game for 1 game, (little over a hr) watched some netflix went back to the game and had the same issue. Ive tried unplugging the hard drive and unplugging the Ethernet cable it still freezes everytime right after the loading screen. What else is there to do? It is the only game my xbox freezes with.
