Shoop

Well I have figured this out finally... spent almost $400 replacing parts tonight but at least I know what the issue is now... and boy do I feel stupid... 
 
bought a new cooler(replaced stock cooler that came with cpu to Noctua NH-15DS), bought 4 new case fans(two to replace the failing case fans already in the case and to add two intake fans in the front), and a new and higher power supply (went from 650 non modular to 750 full modular). 
 
at my local micro center I talked to a tech, and show him the few clips I have of the sound going off... he instantly tells me it’s my UPS and not likely anything inside the computer... however... being the stubborn IT admin I am, I decide to walk over to the service desk and pick their brains... the service tech told me it would be 40 bucks to leave it there for 6 days for them to look at it... and then charge me based of their findings... I kept talking to the service rep and he suggested it was most likely my power supply as it was older than the other components in my computer and could be failing... but wouldn’t offer to test it in store (I had brought my computer in with me on the off chance I could get some one to look at it in store)... didn’t like the idea of walking out of the store without my computer and having to pay who knows how much for an issue that isn’t/wasn’t easily replicable from my end... 
 
Went back to select the parts I was initially looking at and talked to the same guy before. Told him I was going to go with the internal components first(again, stubborn IT Guy)... and that based on my testing I would come back and get an UPs if needed... 
 
fast forwArd a few hours after I had gutted and rebuilt my computer... power it up.. launch wow and BOOM! The sound came back instantly.., 
 
however when the sound started I looked at the UPs and noticed that it was a solid yellow light instead of the usual green... 
boy did I ever and I mean ever feel like such an idiot..., 
 
to sum it all up... I never suspected that it was an UPS alarm even though I have heard that alarm countless times in my years of IT work.., 
 
thanks for the input earlier, just wanted to circle back and update yAll on the root cause of this issue... I could have spent a lot more than I did today... but at least my computer will now be much cooler ¯\_(ツ)_/¯ 
 
im gonna have to Go back to micro center and make sure I give that guy credit and props... had I not been as stubborn i could have spent much less money today to fix this issue altogether... ugh.
