It's a laptop with an i7-4700MQ processor @ 2.40Ghz, I have 8GB of ram, a 2GB graphics card, and I am running Windows 8 64bit.

The CPU is clocking at 3.2Ghz when I don't have anything open. I have looked in the 'Task Manager' to see if there is something running in the background and there isn't. Here is a pic of the processors performance [1] . Normally it would clock in at around 0.80Ghz when doing nothing.

I have tried turning it off and on again twice but that hasn't worked. Can you help me?

I would suggest in your BIOS its related to the turbo boost.

How do I fix it? It shouldn't be doing the turbo boost unless it's required.

I fixed it, I feel stupid now. I had it on the wrong power setting, must have changed it to the wrong one.

In the future, you can set your power profiles to have the GPU max at 99%, which would stop the CPU from entering turbo boost.

You can also set your power saver to use 0% of your CPU, that way it uses the minimum clock speed it can run at, which is probably still fast enough to make basic tasks run smoothly.
