No, you are looking for hardware issues especially around the bios chip.

Thank you very much, maybe my bios is faulty, currently my original bios starts blink code 3.6 led.

I tried your bios it only starts once then turns off, and can't turn on the power.

Thank you for your help !

I was thinking of using this http://youtu.be/FQszDbr973I?si=KmiT-pir-Xp0yszb guide to extract the bios bin file from the bios that can be downloaded from the DELL support page, does using that bios work or it must be the BIOS that is currently installed on my system thanks can the original bios be backup with software?
