Why does my CPU randomly spike?
At first it happened when I was playing games and sometimes movies. The CPU would spike up to ~100% randomly and the FPS in-game would be horrendous.
Now I've noticed it happens randomly, when I'm on the internet or even staring at pixels on my screen.
I've checked all processes when it happens and sometimes it seems to be the game/video I'm playing. But when I close it the CPU still lags for 2 or 3 minutes thereafter. And when it spikes for no reason, all my processes are using 0%, but the CPU is still 100%.
I thought it could be overheating so I got a fan for my laptop, I even cooled it with ICE PACKS. It seemed to help a bit but still have the problem.
Any suggestion?

If it was a heat problem the CPU usage would not be at 100%, if anything it would reduce the CPU to try and keep itself cool.
What antivirus program do you use? If you have Norton or Mcafee then that will almost certainly be the problem, if not it sounds like your computer may be installing updates or something in the background. In device manager click the button at the bottom that says show all processes and that should show up a whole load more and one or more of them will be contributing to your CPU usage.

you ought to have too many classes open and that must be the priority. you will possibly be able to truly have a scourge (key-word: ought to). As for the spike on video games and fps drops, which means your cpu is getting used to its fullest, and because it can't pass greater, it drops in physique costs whilst it does want greater power.
