Computer Crashes first time every time I turn it on after loading a game

[Jordan Squire]

As stated in the title my PC crashes every first boot, only after I load up a game or a very demanding piece of software. However after the PC crashes and boots itself back up I wont experience any problems at all until I manually turn the PC off and back on then it repeats itself. Put up with it for the past 3 months or so but it's getting annoying having to "forcefully" crash my PC by loading a game and waiting on a crash before I can properly use my system.

Just the last 3 months...what changed? Windows 10 April update?

Please check Reliability History and crosscheck what you find in Event Viewer 'errors' - does anything recur as an error?

Have you turned off 'automatic restart on error' so you can see error report (if any)?

Have you tried removing video drivers using DDU ( https://www.techspot.com/drivers/driver/file/information/17830/ ) and installing fresh downloaded from nVidia?
