I've been getting the VIDEO_TDR_FAILURE BSOD for about a month now. It generally occurs when I try to start a game. I've had it happen on Minecraft and Galactic Civilization 3, but oddly never on Ark Survival Evolved. I have a Geforce 840M on an Acer Aspire V. I've tried running with the internal GPU disabled to no avail. Reinstalling the graphics drivers, even using the Display Driver Uninstaller, has thus far yielded no results. Thank you for your time and assistance.
