I'm sure it's nothing serious but the more you know right?
Well anyways, Thanks in advance,

If it's not affecting any of your functions then it's best left alone. However I'd ask you to run malwarebytes, run a virus scan and also make sure your motherboard BIOS is up to date. You might also want to see if a repair install alleviates the issue.

Speaking of motherboard's, please pass on your full system's specs.

I get a sound randomly aswell, Sounds like from windows 7 when a file has finished transferring, I did run a virusscan with "Comodo Firewall and sophos home "
I will install MWB now and make a scan ill be back with the results
Update: Found some cracker i didnt know i had,
I deleted them and after a restart same task again so after 3 restarts they were gone.
Hopefully for good.
