Hi Jovan Tomic,
Thanks for choosing Microsoft Community.
In your description, you are experiencing a black screen for a few seconds while using Alt + Tab.
If you can, please provide me with a screenshot or take a picture of the black screen you are experiencing so that we can determine the problem for you.
I note that you have used the latest drivers and installed the latest BIOS. thank you for the effort you have put into resolving this issue, and I do understand that the current situation is frustrating.
Did you have more windows open or a lot of tasks running when you had this problem?
Please open Task Manager by tapping Esc + Shift + Ctrl at the same time to see if the system is currently using more system resources (CPU, GPU, RAM, Hard Disk usage), if so, please reduce some unnecessary tasks to lighten the burden on the system and then check if the same problem occurs.
If you have this problem during normal system usage, it could be an error in your graphics card driver, please try to reinstall the corresponding driver or use an older version.
You can also refer to some of the steps below
Adjust NVIDIA Control Panel Settings
1. Open the NVIDIA Control Panel:
- Right-click on your desktop and select “NVIDIA Control Panel”.
2. Manage 3D Settings:
- Go to Manage 3D Settings.
- Under the Global Settings tab, set the Preferred Graphics Processor to High Performance NVIDIA Processor.
3. Configure G-Sync:
- If G-Sync is enabled, please try temporarily disabling it to see if that solves the problem.
Try Full Screen Optimization
1. Locate the game's executable file:
- Navigate to the game's installation folder and right-click on the executable file (.exe).
2. Disable full screen optimization:
- Select Properties > Compatibility tab.
- Check the “Disable full-screen optimization” checkbox.
At the same time, this may be caused by some third-party software conflicts. To troubleshoot this possibility, I recommend trying a clean boot which starts Windows with a minimal set of drivers and startup programs. It can be used to determine whether a background service or program is interfering or causing a problem.
These steps of "clean boot" might look complicated at first glance. However, to avoid any trouble for you, please follow them in order and step-by-step.
Please test the clean boot with minimal software to see if the same problem occurs.
I noticed that your current system version is 24H2, Microsoft has not officially launched this version yet, and the already launched 23H2 currently has more stability, please backup your data and try to roll back to 23H2, if you can't, please refer to the following link for a clean install of your system (installing version 23H2)
