I've never had this issue before until recently, it always happens shortly after I boot Subnautica and it's driving me crazy...
After a while I'm met with a black screen and a continous buzzing sound comes out of my headphones.
I tried monitoring temperatures and, for the little time my computer was on, I never rose above 40 celsius for my cpu and 60 for my gpu.

My current build:
Intel - Core i5-6600K 3.5GHz Quad-Core Processor
Gigabyte - GA-Z170MX-Gaming 5 Micro ATX LGA1151 Motherboard
Corsair - Vengeance LPX 8GB (2 x 4GB) DDR4-2666 Memory
Crucial - MX200 250GB 2.5" Solid State Drive
Seagate - Barracuda 1TB 3.5" 7200RPM Internal Hard Drive
Sapphire - Radeon R9 390 8GB Nitro Video Card
EVGA - SuperNOVA G2 750W 80+ Gold Certified Fully-Modular ATX Power Supply
Asus - DRW-24B1ST/BLK/B/AS DVD/CD Writer
Intel - 7260HMWDTX1 PCI-Express x1 802.11a/b/g/n/ac Wi-Fi Adapter

I ran prime95 and met no problems, as well as hd tune for my disks.
I cleaned my drivers with DDU and installed the most recent ones. I'm open to suggestions on tests to do and ways to solve this problem. Thanks in advance.

You’ve isolated the issue to your GPU now so that’s a positive. It could be one of two things: either your graphics card is on the fritz or your PSU is.

If you have another PSU or if you can borrow a buddy’s PSU then swap it out and run the test again. You could also try taking your GPU out and testing it in a different system, too.

I did that and indeed, after running for 3 minutes smoothly wit 130 average fps, it crashed as I mentioned before. After shutting it down forcefully, I opened the case and re-plugged in the gpu wires, making sure they all clicked and all the slots were taken. After that I ran FurMark again but still crashed within minutes... The cable itself doesn't seem damaged, maybe I'm making some huge and dumb mistake that I'm not seeing.
