My AMD 6300 makes a choppy weird sound that is really hard to describe but its done this for about a year and the pc runs all my games great but sometimes the noise will stop and the frames will just tank to about 5-10 fps for 5-8 seconds then the noise starts again and it returns to 60fps. If anyone can explain why it does this or a way to fix it please do.
It's not the CPU, it's either GPU or motherboard, there exists an occurence named "coil whine". Google that if you are curious.
Please provide more info on your config, like system, exact cpu, cooler, OS, drivers, GPU... and stuff
