In the last 3-4 days, my XBox 360 is acting funny. It takes FOREVER for a game to load from the CD and when it finally loads, I'm disconnected from XBox live and asked to patch the game (it does not matter what game, MW2, MW, Vegas 2, Godfather 2, etc). Yet, it won't download and my machine runs very slow for days afterwards. I've done the cache clear procedures listed here and the system speeds up some but it still takes forever to boot the game and I'm still disconnected from XBox live when the game starts. The games play fine with no lag; however, I just did get an original XBox game (Alien vs Predator: Extinction) and while it's on the supported list, my machine won't play it (This game is not supported). It's an original disc, not a copy or burn.
I'm thinking the HDD may be dying (it's almost full but doesn't list anything there over 1 MB to delete) or is in dire need of reformatting. If I reformat it, I'm afraid the machine will no longer work.
Any ideas or suggestions are welcome. Thanks!
