I do tend to play for extend periods when things come out, but i keep them in good shape outside of that, off carpet, in an open space, cool enviroments, the best i can figure is that i just played way too long at a time. however, knock on wood, i only ever restart my mac after new hardware upgrades or software, (up time 4 months right now) and i have only had 1 problem in 4 years, (A faulty ati card when it shipped)
come play minecraft @ mcg.hansrotech.com
