hey guy i just started getting this problem and i didn't read all 120 pages so i'm just assuming when i say this but i think so far, i got it the worse. let me start from the beginning. on tuesday, july 21, 2009, i was playing halo 3 for a couple hours then went to sleep. i left the game in there, even though i knew it can cause scratches, but i didn't know it would screw up my 360. so on wednesday, july 22, 2009, i tried to play again and now i get the unreadable disk message. i'm like damn i shouldn't have left it in. so then i go back to the dash board and it freezes. turn it off, turn it back on, then sign back in. decide to see if my DVD drive was messed up so i put in armored core 4, works perfectly. i take a look at my halo, no scratches, and i clean it with a soft cloth just in case, the cloth i use to clean my iPod Touch. pop it back in and i get the message again. then it freezes when i press A for the message to disappear, it doesn't even make it back to the dashboard. so i turn it off, turn it back on, then try to sign back on. but when i sign in it tells me i need to update my xbox or it'll sign me out of XBL. i say ok and do the update. after it downloads the update it restarts my 360, it freezes. try signing back in on my brother's account and same thing, asks for update. on some occasions, like 1 every 5 times, it'll not freeze. and when it doesn't freeze i'll play UFC Undisputed, Armored Core 4, Tales Of Vesperia, as well as other games smoothly. turned it off when i'm done and works fine when i turn it back on and play games. but when i popped Halo 3 in again hoping it'll work, it freezes my 360 again.after updating it about 3-4 times and working back to normal i don't put halo 3 in anymore. thinking it's all good as long as i don't try to play halo, just earlier my brother wanted to watch something on netflix so he turns it on and signs onto his account. asks him to update and freezes on him. i like playing Halo 3 and i like Xbox 360 but there's obviously something wrong with Halo 3. Halo 3 is causing something in the 360 to malfunction. Of course that's my theory because of my experience starting just 2 days ago. Well to see if my Halo 3 is corrupt somehow, i'm going to ask my brother in-law for my old 360 that i fixed, it had the no-video. and if halo 3 works perfectly on that 360 then i can assume it's the 360 malfunctioning by itself or just due to the fact that i left it in. and in order for me to prove that i would like others that had problems with halo 3 and xbox 360 not working together to post what their activity was with the 360 before it malfunctioned. in order to fix this we all need to work together. and i'm hoping that after 120 of this problem that bungie and microsoft are doing something to fix this too. if not i'm switching to PS3 because this is my second 360, first had RROD and no-video within months after i got it back from microsoft. and now this second one is really ticking me off.
