This means the POST procedure does not even start.

This means (basing on the Dell's information) that the CPU is faulty. However, sometimes this error appears when the BIOS is corrupted so please reflash the BIOS with different file (do not forget to save the original one for ME Region and DMI data transferring).

If the different BIOS did not change anything (still 7 beeps) then the CPU is most likely faulty.

Dla 4 generacji CPU 1,75V na tej cewce jest w normie.
Być może uszkodzona jest sama w sobie kostka bios i trzeba ją podmienić.
Próby uruchomienia po podmianie wsadu bios były robione z odpiętą RTC (zalecane)?
