What I found is that it's often connected to a corrupt driver. You can either try updating to the latest graphics driver or uninstall the current one and restart the laptop. Of course you'll want to make sure you've first done the usual maintenance to rule out a heat issue. With laptops, a few blasts from a can of air designed to blow away dust is the easiest temporary fix. Good luck.
My laptop (HP G42) crashes with a blue screen error 0x00000116. I have tried reinstalling the display driver with no luck.
I am unable to figure out if this is a software issue or a hardware issue. How do I figure that out ? I have the error details and dump files with me as well, if someone can review and then comment - will send that across.
