Hello all.
The build consists of a AMD FX 9590, 2x XFX Radeon rx480, 16bg ram, MSI 990FXA gaming mother board, and 850watt psu. As well as the whole thing being cooled by a 360 Captian liquid cooler. The 3 fans on the cooler and the 1 for the case is what cools it. The temps right now are at 80 for CPU and Mainboard and 132 for the GPU. These are in F. And the fans are at 2000RPM. The build is not under any high stress and only freezes at random.
My main question is, well, how do I fix this. Any tips or help will be perfect.
I am new at PCs so if anyone can dumb it down id be perfect. Thank you.
