Dell SupportAssist Pre-Boot System Performance Check

Dell SupportAssist is an essential tool for diagnosing issues with your computer before the operating system even loads. Running a pre-boot system performance check can help identify hardware problems that may hinder your device’s functionality.

To access SupportAssist on your Dell computer, restart your device and press the F12 key during startup. From the boot menu, select SupportAssist OS Recovery to launch the pre-boot diagnostics. You’ll then be guided through a series of tests that evaluate system performance, allowing you to troubleshoot potential hardware failures proactively.

Keep in mind that regular checks can improve your system’s responsiveness and reduce the frequency of errors. If you encounter the message «Your system is repairing itself, please wait,» it typically indicates that the system is attempting to correct an underlying issue automatically, which might take some time.

Common Mac Troubleshooting Techniques
