Windows 10: PC Freezing then resetting when closing games or tabbing out, what do I do??

I just built my second PC, it’s been somewhere around 3-4 years since I built my last one, and I thought spending more money would result in less issues but here I am needing helpAnytime I load a game, it boots up fine. I can play for a while and no issues 2-3 hours roughly then all of a sudden, crash. Game cuts off and then it freezes. Next, my pc resets itself. This happens on two instances. That and when I tab out or close a game also. I’ve updated pretty much everything and have ran DDU. Not sure what I am to do. I have about 5k in this build so I’m trying not to get more frustrated than

:)

 

PC freezes after tabbing out/closing games.

Has the issue still occurred?

For me it happens often as I use HDR on a monitor. (2 Monitors).
It recently happened with the latest Nvdia Drivers. Even rolling back does not fix the issue.

Alt-Tabbing during a game will freeze up both screens for me.

 

PC freezes after tabbing out/closing games.

As of two days or so ago my pc completely freezes when tabbing out of full screen and borderless windowed games. It feels like it began after I was messing around with making my tv my main monitor and switching it back and forth. All of the screens freeze and I get no responsiveness from my mouse/keyboard. I can still hear the game/discord but my mic stops working too, which is so weird. I updated my graphics drivers, double checked settings in nvidia control panel/windows settings, and now I don't know what else to. If someone can give me a start on what I can do, I would deeply appreciate it.

Freeze and reset on close apps

Hi,

yesterday evening I've found a new problem: when I close any apps using the "X" button in the right top, the Diamond freeze and I must reset it, instead if I can close the apps using the Exit voice from the internal menu, the app close correctly.

No freeze or reset if the "OK" button replace the "X".

I've got the same problem if I try to open the application management menu that appears only in the home (with the list of open apps and the 3 icons). I click on the "little arrow" in the right top and the Diamond freeze.

If I go to Start -> Settings -> System and then i click "Managed Programs" the Diamond reset.

I think is a problem of Windows Mobile.

Anyone had the same problem?

Thanx
