Samsung's Built-in Diagnostics Explained

Beginner Samsung Applies to: Windows 10, Windows 11

Available through the Samsung Update app inside Windows — with real limitations compared to Dell or HP's pre-boot options worth knowing upfront.

Before you start: save any open work and note down what you were doing when the problem started — that context helps if you need to search further or ask for help.
  1. Open the Samsung Update app (usually pre-installed, search for it in the Start menu) and look for its diagnostics or PC health check section.
  2. Run the available hardware checks from inside Windows — this covers common components, though Samsung's pre-boot diagnostics (tests that run independently of Windows) are more limited than what Dell or HP offer on their own hardware.
  3. If Windows itself won't start and you need to test hardware independently of it, a general Windows Memory Diagnostic or a manufacturer-agnostic bootable tool is a more realistic option than looking for an extensive Samsung-branded pre-boot equivalent.
  4. If Samsung Update isn't installed and you want it, get it from the Microsoft Store or Samsung's own support site directly, rather than a third-party download source.
  5. A hardware test that passes rules out the specific components it actually tested — it doesn't rule out a software-level cause for whatever symptom prompted you to run it.

Frequently Asked Questions

Why are Samsung's pre-boot diagnostics more limited than Dell or HP's?
It's a difference in how much each manufacturer invested in dedicated bootable diagnostic firmware — Samsung has focused more on their in-Windows Samsung Update app for hardware checks rather than an extensive standalone tool.
Is the Samsung Update app the same as Windows Update?
No, they're separate — Windows Update handles the operating system and Microsoft-distributed drivers, while Samsung Update specifically manages Samsung's own software, drivers, and diagnostic tools.
