I am currently undergoing similar issues, only when gaming. As soon as the GPU is stressed/used in any way my computer will die and when looking in The Windows Event Viewer, I find the error Kernel-power 41. This is caused by a power issue. However, in my scenario I have tested other power supplies and the problem persists, leading me to believe the room has faulty outlets.
check your windows event viewer for the most recent critical error. This will give you more information about what is causing your crash.
