Dear Semenyuk Bogdan,
Thank you for reaching out regarding the lsass.exe error you’re encountering during gaming.
This issue can be critical, as lsass.exe (Local Security Authority Subsystem Service) is essential for system security and authentication.
Let’s go through some troubleshooting steps to help resolve this issue.
Step 1: Update System and Drivers
- Update Graphics Drivers: Visit the manufacturer’s website (e.g., NVIDIA, AMD, Intel) to download the latest graphics drivers. Alternatively, you can use tools like NVIDIA GeForce Experience or AMD Radeon Software for managing updates.
- Update Other Drivers: Open Device Manager (Win + X > Device Manager). Check for any devices with an exclamation mark and update their drivers accordingly.
Step 2: Disable Potentially Conflicting Software
- Press Win + R, type msconfig, and press Enter.
- In the System Configuration window, go to the Services tab.
- Check Hide all Microsoft services, then click Disable all.
- Go to the Startup tab and click Open Task Manager.
- Disable all startup items.
- Close Task Manager and click OK in the System Configuration window.
- Restart your computer and try running the game again to see if the problem persists. Disclaimer: A “clean boot” starts Windows with a minimal set of drivers and startup programs. It helps to determine whether a background service is interfering with your game or program and to isolate the cause of 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 so that it will help you get back on track.
Step 3: Check and Repair Game Installation
For Steam Games:
- Open Steam and go to your Library.
- Right-click on the game and select Properties.
- Go to the Local Files tab and click Verify integrity of game files. This will check and repair any corrupted or missing game files.
For Windows Store Games:
- Open Settings > Apps > Installed Apps.
- Find the game in the list, select it, and click Advanced options.
- Click Repair.
Step 4: Consider System Restore. If the issue started recently, using System Restore may help:
- Go to Control Panel > System and Security > System > System Protection > System Restore.
- Choose a restore point prior to when the issue began.
If after trying these steps the problem persists, it may be necessary to seek professional technical support for further assistance.
