Many times when a game starts up with no problem but routinely shuts down after a period of time it's a heat issue with the GPU. A good program to check temps is
GPU-Z. When you install/open that program, click on the 'Sensors' tab. Then start up ED, play till it crashes and then check the GPU temp graph...it'll show you the temps over the last 10 minutes or longer.
Other causes could be corrupt driver uninstall/install which is rare but can happen. In that case I would use a driver cleaner/sweeper to make sure all traces of your old AMD driver is removed as sometimes bits and pieces get left behind in the registry.
DDU is a good one. If it was me doing this method I would 1) create a restore point 2) remove current Nvidia driver 3) run DDU to clean both Nvidia & AMD drivers to make sure every piece is gone 4) install current WHQL Certified Nvidia driver, not Beta driver
