  • Hi HJones14,

    It is unfortunate that the computer has loud fan noises. Request you to try following the below steps which might help:

    (1)   Make sure that the computer is kept on a flat surface.

    (2)   Clean the air vents with a can of compressed air.

    (3)   You may then use the below link and update BIOS:

    (4)   If none of the above steps work then you may use the below link to run a hardware diagnostics:

    Note: This applies to Inspiron 3721 system also.

    Make a note of the error codes that appear (if any).

    If none of the above steps work do send me the system service tag via private message. I will check and see what can be done.
