Lately my pc has been having freezes at seemingly random intervals. I game most of the time, but it's also frozen while simply browsing chrome. I don't think it's an overheating issue. I checked the temps and my gpu is fine. Cpu max is at 80C while gaming, 50C while idle, which is high, but should be ok. I've checked my RAM with the windows diagnostic and it's fine as well. There's no slowdown or anything prior to the freeze. PC is running normally, then immediately it freezes, and as mentioned there's usually a consistent buzz from the headphones. Pc noise doesn't change. I have to hard shutdown it at freeze.
