Dell has a suite of self-diagnostics that is built into Notebooks, Desktops, Servers, and Windows-based Tablets. These are called the Dell SupportAssist Enhanced Pre-Boot System Assessment (SupportAssist ePSA), Dell Enhanced Pre-Boot System Assessment (ePSA), or Dell Pre-Boot System Assessment (PSA) Diagnostics.
When you cannot boot your computer, you should try to run the self-diagnostics first. Any error codes that are provided by these tests can go a long way toward troubleshooting your issue.
