High CPU usage on multiple OS and CPU's

May 2, 2017 at 11:37:05
Specs: Windows 10
I was having high cpu usage on windows 10 with an i5 4690 so I bought an i7 4790k and my cpu usage is still ridiculously high and by high I mean 90-100% when I go to a page or watch a video. I was wondering what would cause this. I was thinking that I had a bad cpu and now I don't know what's the issue.

My motherboard is a z97a.

More than likely, your system is infected. Why would you suspect the CPU?

I've ran virus scans, and it found nothing at all, and I reinstalled windows 10 too, still the same problem..

I was suspecting the cpu to be the problem because it was maxing out the way it did, but since I tried with another cpu and the same problem still occurs.. then I guess it must be something else. I have no clue what it can be at this point though. Could it be my ram/powersupply? or software related?

"I reinstalled windows 10 too"

Did you delete all the partitions, create one or more new ones, format, & then reinstall completely from scratch? Have you checked Task Manager to see which process is hogging the CPU?
