This is going to be a very vague description because this sound is literally impossible to record. It's not loud enough to be heard over the sound of my PC's fans, so stick with me.
 
Yesterday my desktop computer started making really odd clicking/cricket noises. They're very high pitched(but very quiet!) and occur in this odd pattern. The sounds occur in the pattern about every half a second in groups of 6's or 7's before pausing for about a second and starting another group. I'm 100% positive they're coming from my PC because they don't occur when it's off. 
 
As someone with misphonia, these sounds are not ignorable and genuinely makes it impossible to be in the same room with my computer when they occur. I've tried cleaning out my entire computer of dust and this did not yield any results. 
 
I'm almost positive it isn't an issue with a fan. My case fan and GPU fans do not work in the first place, and I've thoroughly inspected my Cooler's fan and there are no loose wires sticking into it or are even near it. It's as lonely as a fan can possibly be in a case. My temperatures are also okay, I only get about 19-20 C without any programs running.
 
I've done some extensive research online and have listened to many of the examples of sounds people have found with their PC. HDD Failure, CD Drive failure, etc, nothing even comes CLOSE to matching this sound. It's extremely obscure. I can probably compare it to someone scratching a piece of chalk up agaisnt a blackboard.
 
I'm also unsure of where in my PC it's coming from. It's honestly impossible to tell.
 
Computer Specs:
Case: Cooler Master Scout 2
GPU: ASUS GeForce GTX 960 2GB
PSU: Cooler Master V750
RAM: 8GB of Corsair RAM. Two sticks of 4GB. 
HDD: 3TB Seagate
CPU: AMD 8350
Cooler: Cooler Master EVO
Motherboard: ASUS M5A99FX AM3+ AMD
 
I built this computer in August of 2015. I wasn't expecting to have obnoxious issues like this for sometime.
 
If I really need to find a way to record it I will, but I honestly think it'll be REALLY difficult to considering how quiet it is and the fact I dont know where it's coming from.

I would try unplugging your fans one at a time and see if the noise goes away. It could also be the motherboard chipset based on your description, but there's not much that you can do about that.

Like I said, my GPU and case fans don't work for whatever reason, despite being plugged in. And having my Cooler off isn't exactly optional.

I've run across a few of these "mysterious" noise coming from various desktops.  Most were tracked down to the hard drive and resolved by loading the backup.  It appears that during the subsequent loading of a program, the writing to the drive reached a point where the heads rested idle over a spot that made a squeak just barely audible.  In the early days, some manufacturers used head movements on the hard drives in a manner that it sounded like a beep, signifying the end of a task.  I would look closely at the task manager and see which processes are active during the noise and that could be the clue to solving the problem.
