So I recently bought Rust on the Steam autumn sale(have bought it before but refunded it) and I'm experiencing this issue when I lower the graphics and every other setting to low or medium and try to go on the Rust server list/try to join a server my PC's screen goes black and the fans go to 100% speed, to be able to see my screen again I need to force shutdown my pc and start it again.

I have:
CPU: Ryzen 5 1600 (12nm)
GPU: RX 590 8 gb Phantom Gaming
MOBO: Gigabyte B450 S2H micro atx
RAM T-Force Vulcan Z 16gb (2 x 8)
PSU: Thermaltake Smart RGB 700 W 80+
Drives: 1 x HDD and 2 x SSD's.

I suspect that it gets caused by my GPU overheating but I'm 75% sure, ran some test on FurMark and it seems to black screen always when i reach and stay on 83c for a little bit the GPU is 3/3.5 years old and i was thinking of changing the thermal paste and vram pads. Any help would be seriously appreciated!
