Windows 10: PC Crashes after closing a game or alt-tabbing off of it

So basically my computer just freezes or stops working as soon as i close a game or tab out. It just completely freezes and becomes unable to restart etc. So because of that i just press power button to turn it off and turn it back on.Other than that my game has no problem, no fps drops, no stutter, nothing. Everything is wonderfully fine while playing the game or doing my work on the computer.I update my drivers as soon as they release new versions of them and i have done a virus check on my computer which resulted negative.Any help to resolve the issue is much appreciated.System;Microsoft Wi

alt + tab not working

Alt-Tabbing in & out of games does not always work. It can also crash games in some cases.

 

Alt + Tab = Crash

Good evening,

It appears that Windows 10 keeps crashing whenever I Alt + Tab out of a game and then attempt to go back in. When I Alt + Tab back in I'm met with a black screen. Then Windows 10 freeze and I can't do anything.

Steps to reproduce:

(1) Start game

(2) Alt + Tab out

(3) Do whatever in Windows 10

(4) Alt + Tab back in

>>>Black screen

(5a) Ctrl + Alt + Delete to end process of game

(6a) No clickable buttons in Windows 10 (can't even shut down)

(5b) Ctrl + Alt + Delete

(6b) Shut down (just spins indefinitely and doesn't actually shut down)

This is a on a brand new copy of Windows 10 (not an upgrade). My current specifications are below:

-5930K

-MSI SLI Plus X99 Motherboard

-16 GBs 2800 MHz RAM

-2x NVIDIA Titan X GPUs

-512 GB M2 SSD

-1600w EVGA PSU

Please advise on what is happening and if this will be fixed soon.

 

Weird alt-tab out of fullscreen games.

Hi Simon,

The multitasking capability of a game depends on the total memory of your computer. If you have large amounts of RAM on your computer, it can multitask heavy programs easily like high-end games. To ensure that we can provide the appropriate resolution
for your concerns with the alt-tab function, we’d like to ask you a few questions:

• What were the recent changes made on your computer before you experienced this issue?
• When did the issue start?

• Have you pressed the alt-tab key during you play Rainbow Six Siege? Or it just happen without pressing it?
  
• Does the automatic ALT-TAB behavior happens on other games?
• Do you have any other programs running on your computer while playing?
• What is the anti-virus program you're using?

• What is your device or system specifications? To know, follow these steps:
  1. Press Windows + S and type
     About your PC.
  2. Send us the information listed under Device specifications.
  
  

Moving forward, if you're multitasking while playing, we recommend that you play this game only without doing other tasks. Pressing ALT-TAB or performing a multitasking interferes with the performance of your video card, especially if you're running a heavy
game like Rainbow Six Siege. It will generate screen viewing issues like intermittently switching your game screen between your desktop environment.

For now, restart your game and do not press ALT+TAB while playing. This will allow your video card to dedicate its graphics performance on the game only instead of your desktop environment.

If you would like me to provide additional advice, simply respond to this thread. I will get notified and I’ll reply to you as soon as I can.
