Make sure you have the latest version of Windows 10
Updates often fix compatibility issues and security vulnerabilities. Therefore, it is recommended that you download them frequently.
In addition to updating Windows 10, we recommend that you update your drivers regularly.
Since BSoD problems are often caused by faulty or incompatible drivers, make sure the drivers for your motherboard, network card, and video card are up to date to avoid the RDR_FILE_SYSTEM error.
If you need to update your drivers, the easiest way to do so is to manually download them from the hardware manufacturer’s website.
