Hi,
first time using this site.

I have recently started to have a few issues with my cpu. My CPU randomly spikes when doing anything. It goes from 1 percent to 10-90 percent when having nothing open. When playing games its about the same but starts from about 40 percent. It lags games, i have over 150 fps, so i know its not my GPU.

I have tried re-installing the operating system and still no luck. I have recently upgraded my hard drives to a SSD for the OS and a hard drive for applications and games, hoping it would solve/help with the issue, but still the issue has not been fixed.
I have also checked the temps and if any applications are using up all the CPU and nothing is.

Before this started happing I had no issues with it. But a few months before this issue 2 of my ram slots did stop working. This happened after i moved my computer from a different country.

My CPU is a intel i5, the desktop is about 2 years old.

Could it possible be the motherboard?

Any help/advice would be great.
Thanks
 

I have installed a completely new copy of windows and it has still not fixed the problem.
 


I had the same issue before, reinstalled windows and completely wiped my SSD. Still spiking CPU and I found that Windows problem reporting was using 99% of my CPU! It was windows problem reporting
 


How did you fix the problem?
