I have a refurbished Xbox 360 Arcade that had the Red Ring of Death (error code 0103). I took the x-clamps out to fix it, and it worked perfectly. Now, whenever I insert Halo 3, the title screen comes up, but then it freezes. I have tried it with and without my 20 gig hard drive, but to no avail. I moved my hard drive to my Xbox 360 Pro, and inserted Halo 3 in that one, and it works fine, so i know that it isn't a hard drive issue. I need to know what could be wrong with the refurbished one.
