I have a systemax computer serial #106279177. It will not boot up. I placed the diagnostic cd to test and completed that. Re-tried and it did not boot. The message states to place the cd. When i do it repeats the the same process. press R to restart or T to test. I have done this several times with no success. Any ideas?

The time it takes for a Dell Latitude E6400 to complete a diagnostic boot can vary depending on several factors, including the specific hardware configuration of the computer, the number of diagnostic tests that are run, and the condition of the hardware.
Typically, a diagnostic boot on a Dell Latitude E6400 can take anywhere from 5 to 20 minutes, depending on the specific model and the complexity of the diagnostic tests.
The diagnostic boot process on the Dell Latitude E6400 starts with a pre-boot diagnostic test that checks the basic functionality of the computer's hardware, including the memory, hard drive, and keyboard. This test typically takes only a few minutes to complete.
After that, the system will run a more extensive set of diagnostic tests which include PSA (Pre-boot System Assessment) and ePSA (Enhanced Pre-boot System Assessment) . These tests take longer to complete and check the more in-depth hardware such as the system board, processor, and other internal components.
You can also run an extended diagnostic test that checks all the hardware components of the computer, including the memory, hard drive, and other internal components. This test takes longer to complete and is typically used when the computer is experiencing hardware-related issues.
Please note that the diagnostic boot process can take longer if the computer is experiencing hardware-related issues, and if the computer fails the diagnostic tests, it will stop the boot process and show an error message.
