I get a lot of crashes, but they always seem to be when I go to bed. I just realized, when I turn off my LG monitor it disconnects not only the monitor device (which is odd, never had a modern monitor remove from devices when in power off mode/stand bye), but also the USB hub it has, as well as TruColor device driver.
Ya think these things could screw with memory or power, or something, and be why the computer is just restarted? It's always a Kernel Power Fault, which makes me think power management with devices now more than all the things I suspected before.
