Instant Crash - Photoshop - Windows 11

[PhiDough]

I have been having an issue with my PC instantly powering off (no blue screen or anything) very soon after opening Photoshop.  I have recently installed Windows 11, updated everything, and have reset Photoshops settings, but it is still happening.

I definitely have enough hardware, (I9-10xxx, 3080 RTX, 64g ram).

It's a very violent power down almost like you'd expect from a power surge.  

Anyone had similar issues?

I was having a similar problem as  others.  I tried everything including setting the affinity.  Sometimes it would work for a while but the it would fail by just freezing.  Then I was trying to edit with Microsoft Photos app, and the same thing started happening -- system freeze without warning.  This suggested that the problem might be with the Nvidia display adapter.  I have Nvidia GeForce GTX1080 ti.,  I opened Nvidia Control Panel, and under 3D settings, I selected Manage  3D settings.  Scrolling down, I selected Threaded Optimization and turned it off.  This affects threading just as setting affinity does.  It appears that this has solved my problem.

For anybody else coming across this, i9s require good-quality cooling. It's possible that the machine was overheating, resulting in a shutdown. I have an i9-13xxx series with a water cooler. It's important to keep the outside clear of dust. Even a little bit will overpower a water cooler on a hot day without A/C.

Peace.
