I have a Dell Inspiron 7559, and recently one of the fans has started to randomly make a strange buzzing noise accompanied by vibrations. It happens completely randomly, and I've done every diagnostic test and I've cleaned out the vents. Most of the time it works normally, and its hard to reproduce since I can't predict when/why it happens. When it does happen, however, it will slow my games and it takes longer to load models/textures. My warranty expired a couple months ago. I assume something is wrong with the bearing. I've done everything I can think of.
I've had this laptop for around a year and a half now and its worked perfectly until now. I'm fairly upset considering I've had worse, cheaper laptops last longer than this. I have no idea what it will cost to repair/replace the fan but I know it won't be cheap. I just have no idea whats wrong here.
Here's a video of the noise: https://youtu.be/WH7JCfu62Vw
I'd suggest updating the System Setup(BIOS). Please watch Dell video to safely install latest BIOS version in link below:
After updating latest BIOS and the problem still occurred, I suggest updating Chipset and Video drivers in correct order:
I've done everything including updating the drivers yet nothings changed. I've taken compressed air and cleaned the vents yet it affects nothing. I've done every diagnostic test I can use yet it shows nothing wrong
