High CPU usage at Idle.

[twitch904]

So over the last month or so my computer was slowly starting to show symptoms. I fist noticed it when playing league. My fps went from a steady 250 to fluctuating between 60-160 fps causing random "attempting to reconnect" while the ping never moved. I spent a few weeks trying to diagnose when all of a sudden two nights ago it just starting running insanely slow. my mouse would do this slow motion acceleration thing when moving, bf4 started running between 14-26fps and in general it took forever to do simple tasks. My cpu was idling between 50-80% and loading a game would slam it to 100% consistently. I had a buddy look at it last night, and after extensive tests he said the hardware all checks out so he's pretty sure it's not a hardware issue. And after disabling all of my startup processes we've got it down to around 25-30% cpu at idle but it still wont do anything useful. when you load a game it still runs choppy. We also noticed when testing it it seems to run almost smooth until you move the mouse to look around in game. and before this all started my cpu idled around 1-4% with all of my startup apps enabled.

Here are the computer specs.

mobo: Aorus GA-Z270X-Gaming 5 (rev. 1.0)
cpu: Intel Core i5-7600k
gpu: Zotac Nvidia Gefore Gtx 1060 6gb
Ram: G.SKILL Ripjaws V 16GB (2x8GB) DDR4-3000 CL15-16-16-35 1.35V 288PIN Dual Channel Memory Kit


Any help would be greatly appreciated!

Do you mind posting a screenshot of your task manager? Would like to know what is causing your CPU to idle so high.
