What version of Windows are you running? It needs to be bang up to date ideally (1903), along with your nvidia drivers (which should get rid of the tdrdelay reg changes.

Remove all manual over/under clocking and probably reinstall the game. On a 1050 an overclock isn't going to render a noticable improvement in game anyway

Once you've done that, then going over one component at a time is the best thing to do. As I mentioned in my post, try disabling the XMP profile in the MB bios for your RAM. You might find that it is something to do with that that causes these problems. If that stabilizes things, then slowly work your way back up to what the XMP profile is until it falls over again.

If the RAM isn't the issue I'd move onto the GPU. Switch slots if you can. If this fixes it then you probably have a power issue to the first slot.

I am saying all of this however assuming you have no issues playing other games?
