I wonder if this is in any way related to my laptop's tendency to go to sleep, get hot, and then never wake back up when the lid closed OR it put itself to sleep OR it turned the screen off... even when plugged in the entire time. These lock ups would occur every few days and always required me holding the power button to manually reboot. Somehow, me manually putting it to sleep (through Start menu or with the sleep button) is safer (not 100% though), so my current solution is to set the Screen-off and Sleep timers to 166,000 hours (disabling or setting to zero didn't work) and also only close the lid when the laptop is (supposedly) fully off. It's a used Asus that I bought off eBay, so I'm not too invested in figuring it out... but it is annoying.
