My PC is a fairly new, I just built it pretty much. For a couple of months now I've been experiencing very annoying static which causes stuttering in game, and comes and goes while watching videos or gaming. I have tried everything I can think of;

So far I've
  • Rearranged the my wiring set up in my computer around 3 times now
  • Unplugged the HD audio cord from the motherboard (this seems to be a common fix, not for me)
  • Have tried internal, and now an external sound card (neither have accomplished anything)
  • Reseated my graphics card a few times, as well as my RAM
  • Updated my sound drivers through device manager
I might be missing something I've tried.

I just found out that my pin connectors to my PSU have copper coloration on them in the same spots. I am wondering if my PSU is faulty, I've already contacted the distributer.

Additionally, my graphics card seemed to be under intense load a couple times, as the fans were throttled to 100% and my computer black screened requiring a hard reset. This has happened twice, the last time being about a month ago and hasn't happened since. (I play mainly Elden Ring and DayZ, both on max or near max settings and 4k)

The temperature of my graphics card has reached around 85-88 degrees Celsius (hotspot) and around 75-80 is the normal temperature while gaming. I'm not sure if the card is faulty but I've already contacted MSI to check the status of my warranty.

I don't know if it's my motherboard, PSU, or graphics card, but I am really struggling to narrow this issue down. Any help would be greatly appreciated, thank you so much!
