Cracking sounds from cpu or gpu

Is the system running extremely hot when you hear the sounds? If the laptop is under warranty I would be calling Dell tech support, in your region,  for your laptop. I cannot imagine a CPU or GPU making a sound like that but possibly the fan is giving you trouble.

Hi Vamsi2779,

Thanks for posting.  Apologies that your system is not performing as expected.  

Your post does not indicate if you have run a systems diagnostics to test for hardware issues.  Please run Dell SupportAssist, make a note of any error messages encountered, and post back.  Make sure the exhaust areas of the chassis are free and clear of debris or other items that might obscure the fans.  You can use a can of spray air to help clean out those areas.

If there are no error messages, then it could be a possible software or driver issue.  Please check to see that your audio drivers and BIOS drivers are up to date.  

Here is information from the Dell knowledge base you may find helpful.

If the system is under warranty, please contact me privately. Be sure to include your personal information (name, address, telephone, email) and your computer's service tag number in your message. Thanks.

If there is no warranty, then you could contact our Out of Warranty team to get a quote for a paid service call -http://dell.to/1vnT6CQ

The only other source I can think of would be the hard drive especially since it takes so long to shutdown. Have you run diagnostics on your system yet? Restart the system and at the Dell splash screen start tapping F12. Run full diagnostics paying special attention to the hard drive results.

I'm having a very similar issue with my Inspiron 7586 even though I just received it back after Dell official repair ( which lasted 21 days in which I had to study for some exams without the necessary grafics softwares), hope you'll find a solution. I don' know why Dell hates this much a customer who spends more than 1000€ for one of their Laptops! If a one of Dell Custumer Support department saw this, please help me! The support Dell Italia gave me was terribly unsupporting. 

I have been waiting to use my new laptop properly since september!!!

have 5576 here, exact symptoms ever since it was brand new. a mixture of several online discussions points to coil whine. this is not coil whine as i am able to reproduce coil whine when running furmark test.

this is a single click, like if you had very loud mouse clicking, and happens usually when dedicated GPU is turned on or turned off (no constant dGPU on, power down feature is quite useful to me), still i'm not sure if it happens on dGPU or integrated one as the sound appears to come from CPU area.

it appears to be some kind of power-related feature (maybe even thermal-related) as it doesn't happen too often on win7. to reproduce this on win7 i had to unplug both fans and let CPU/GPU temps go to 90C. terminated furmark test, left the system to cool down a bit, until it dropped to 65C, closed furmark (this effectively powers down dGPU) opened furmark again after two seconds and the click appeared.

but something else interesting happened, my CPU/NB overclocked via BUS clock increase as you can see on screenshots during opengl tests. not sure but this might have been an effect of higher board components temperature

however, laptop came with win10 and there the amount of these clicks was much bigger, even if done nothing heavy on machine e.g. watching HD DVB stream and temps were in normal range at that time, about 50-60C, so this defeats thermal-related theory and leaves it open to power-management related.

another thing, in win7 there is no AMD GPIO Controller system driver installed, win7 simply didn't detect device, while on win10 it is present and it could be possibly utilized by various software or kernel trying to power-manage the system thus resulting in more frequent clicking noise
