so... i started getting them about once a day. reinstalled os x, still got them. and they became more frequent... sometimes once every 10 minutes, and the screen would stay black for 2-3 min before i could successfully restart. did another clean install of os x, and vista x64, for fun. vista is far more stable than os x, but i've still gotten a couple BSOD's (about once a day). the kernel panic logs are inconsistent... sometimes it says kernel trap at the top, sometimes some other thing. usually kernel trap. at the bottom, the process it references varies wildly. sometimes airport, sometimes kernel_task, sometimes firefox. i'd post a couple now (have them all saved) but sadly i am running in vista what does this sound like? bad RAM? hopefully it's not a bad disk or a bad logic board/cpu, since i just had my logic board replaced because of the dreaded 8600m debacle, and i just bought a new hitachi 7k320 a few weeks ago. and the RAM would be a bitch too. i run a 2.4 SR (merom - pre-penryn) with 4gb RAM, 256mb 8600m, leopard, vista x64. help me!
