Why does my CPU randomly spike?

Question

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?

According to me there is no connection with ice to settle the issue.
 u need to have a good registerty cleaner which will sort out the matter, therefore i recommend u to have ccleaner which will clean the registery issues, and all history related issues also the issues related to wnidows log files.
also u need to have a good antivirus.

you could have too many programs open and that could be the problem. You might also have a virus (Keyword: might).

As for the spike on games and fps drops, that means your cpu is being used to its fullest, and since it cannot go further, it drops in frame rates when it does need more power.
