I leave my computer on all day. This is a new system Windows 7 Pro, 6 core i7 64 bit, 32MB of ram. Using CS 6 64 bit as well. I've had two crashes happen while being away from the house when returning to my computer and logging back on I have a crash message from Photoshop and have to ok and let the application close. I have to note that my Windows 7 system logs off by itself after a long time of inactivity and I just log on myself again. I have other application open like Windows live Mail, 3D Coat and DAZ Studio but so far no crash with those, the only one seems to be Photoshop CS6. Here's the two reports from Windows Event Viewer:
