i have a 15" MacBook Pro from 2010 (running Snow Leopard), and i'm getting annoyed because the system crashes and the screen turns off when i'm using it, and have no other choice than press and hold the power button to turn it off and restart it. I just want to know if there's a way to fix this; I already sent the laptop to apple, but they told me they never got a crash or any error, but told me that when they test the macs, they use a separate OS so they never get into my stuff, i guess that's why they never got the crash? I formatted the Hard Drive but that didn't fixed my problem. I have no steps to make it crash on purpose on snow leopard, but i know a way to make it crash on Bootcamp (using Windows7), by trying to open Audiosurf. Here's a video (using bootcamp), the first crash occurs at (0:20), and the second one at (2:50): https://www.dropbox.com/s/3racjibxbvs5nxh/IMG_1188.MOV I also saved some panic reports that OS X gives me when the laptop crashes on Snow Leopard, (not sure if this helps): https://www.dropbox.com/sh/qlq90g0kovcvddy/3M3F3OUGMm Hope you can help me , and sorry for my bad english.
