Understanding Dell SupportAssist Pre-Boot System Performance Check

Dell SupportAssist is a powerful tool designed to enhance the operational health of your systems. During the boot process, it can conduct a pre-boot system performance check to diagnose issues before the operating system loads. This ensures any hardware problems are detected early, providing a smoother startup experience. To use it effectively:

• Restart your computer and press F12 to access the boot menu.
• Select SupportAssist OS Recovery to initiate the check.
• Follow the on-screen instructions to assess your system’s performance.

Passing this check means your hardware is functioning properly. However, if issues arise, you may need to follow troubleshooting steps or contact Dell support directly.
