Dell SupportAssist is showing a critical error — what should I do?

Dell SupportAssist is the official utility for system diagnostics and updates. If it shows a critical error (especially during startup or hardware testing), it could be due to:

A hardware issue (disk, RAM, battery, cooling system);

A malfunction in the utility or its latest update;

An error caused by corrupted or outdated diagnostic data.

🔧 What to do:
Restart your system and re-run the test — sometimes the error is a one-time glitch.

Go to Dell’s website, enter your Service Tag, and launch the online diagnostics:
https://www.dell.com/support

If SupportAssist crashes or fails to launch:
– Uninstall it via Control Panel
– Download and reinstall it from the official page:
https://www.dell.com/support/contents/en-us/article/product-support/self-support-knowledgebase/software-and-downloads/supportassist

If the error is related to the drive, battery, memory, or fan:
– Take a screenshot of the results
– Contact Dell service (especially if your warranty is still active)
