A BSOD, or Blue Screen of Death, is a common error in Windows 10 caused by various issues. To fix the errors, the first step is to identify the cause. This can be done by looking at the error code displayed on the screen and researching the code online. Once the cause is identified, the next step is to troubleshoot the issue. This can involve updating or reinstalling drivers, running Windows Update, running a virus scan, checking for hardware conflicts, or running the Windows System File Checker. If none of these steps resolve the issue, it may be necessary to reset or reinstall Windows 10.
