BF4 PC stops responding to mouse and keyboard input

I don't know if this will help you guys but for CPU spikes I found a workaround (on the internet not me myself) is that the CPU spikes can be stopped by disabling the paging file in windows performance options. It does carry the risk of causing errors if you run out of RAM so I'd only recommend this for people with a fair amount (>=8GB).

It worked for my brother's machine and I'm about to do it on mine aswell as I've started getting this problem also. Will update when I have tested it.
