Hello. I have Early 2008 MP 2x3.0, 8800GT, 16GB RAM Before I was on SL rock stable, I would leave the machine on for weeks. Backed up my data and did a clean install of 10.8 (I think it's 10.8.1) and updated to 10.8.2 I have finished it yesterday and while running handbrake several times now the system crashed. Any thoughts? I suppose next time it happens I'll copy and post the error message.
