Running Dell diagnostics
is one way for you to check your computer hardware without any additional equipment and without destroying any data. The diagnostic tests can provide important information that is needed when talking to Dell's customer service personnel. However, some issues can arise when it comes to performing diagnostics on an encrypted hard drive.
Dell engineering has confirmed that DST/PSA/ePSA hard drive diagnostics can be performed on encrypted hard drives, even without an administrator password. While it is true that the data is inaccessible, the diagnostic can access areas on the hard drive that will allow them to test and store results. These diagnostics can also be performed on Bitlocker
How To Run a Dell Diagnostic
Here is a quick run down of how to perform Dell diagnostics across a range of devices.

Run Online Diagnostics
Another option is to run PSA
diagnostics from the Dell Support Site.
Head to the Dell Support Site, and enter your Service Tag

Run the Quick Test
. This may take up to 10 or 15 minutes, depending on the hardware in your system.
Use an ePSA Error Code After Diagnostics
If you have already run the ePSA diagnostics and have taken note of the error and validation codes, then you can log a service call using the Enhanced Preboot System Assessment
You will need to enter the error and validation codes as seen on-screen as well as the service tag of the faulty computer. Simply follow the prompts to complete the process.
