My Xbox 360 has a serious problem. Its a Video issue. I get no picture anymore. The process of this happening was; One day, my 360 flashed a green screen very quickly, and then it was fine. I saw no other signs of problems for about 2 weeks, and then while playing a game, the video went into a black screen. Within about 30 minutes after this happened, the console progressively got worse and worse to the point where you turn the console on and see a black screen after 2 seconds or so. Currently, it turns on, has a screen for 2 seconds and goes black, but when it gets reset, the black screen then turns into a "snowy" screen. I know something is up with the GPU, but my question is, is there still a chance it isn't dead yet? Is there a small chance that something like the M$ thermal paste has been overheated and is now blocking the signal going through the prongs to the board or something? Could there be a chance that cleaning and applying new thermal paste will fix this? I need to know A.S.A.P. because if I need to try to fix this thing fast if its possible. Thanks in Advance.
