Re: Laptop makes buzzing noise and freezes up
In case the buzzing noise is from the fan area, you could clean the air vents of the laptop with a can of compressed air. Also run a built in diagnostics to check for hardware issues.
Kindly find the steps below to perform the H/W diagnostics.
Turn the computer off >restart the computer
At the Dell logo screen, start tapping the F12 key a few times until you see the ‘One Time Boot Menu’ appear.
At the one time boot menu, press the down arrow key to highlight ‘Diagnostic’, and then press Enter to begin the PSA diagnostics. If the test fails, please make a note of any error codes listed. You can also refer to the link below.
Thanks and Regards
