@natnaeldilu The diagnostics code of the LEDs 1_3 for the Optiplex indicates an issue with the memory modules. Remove the memory and clean the contacts gently with a pencil eraser, then reinstall the memory. See if that helps. If not you may need to replace the RAM.
To work on your computer use the Dell Optiplex 990 Service Manual
