Okay so... For no reason, since yesterday I've been having random CPU spikes. It'll be at a regular load like 20-30% and then it spikes to 70ish% and my entire PC lags severely for a few seconds. It happens randomly, usually every couple minutes. It's literally killing me. It's never done this before in my life, since yesterday. I've done what everyone says like finding the process that spikes up, but nothing has worked. I even reinstalled Windows 7 just now, still no luck. After reinstalling Windows 7 - I think it's a hardware issue... Does anyone know?
