I went out tonight and bought screws and washers to fix my RRoD'd xbox. So tomorrow morning I'm going to hit it hard by removing the mb, clamps (going in the trash), and cleaning up the old thermal paste. Then some new Silver 5 with the heatsinks attached with screws and clamping those bitches down. Then a several 10's of minutes overheating it and test. Hopefully this will cure things once and for all. If not I'll be near a mall in the late afternoon/evening and I'll just pickup a new one.
