CPU and slow PC after installing

After i install ESET: Smart Security and then after 20-30 minutes my PC turns really slow.
It starts using 75%+ of my CPU, and when i shut my PC down in the software by logging out etc. i just get a BSOD really quick flashing and then my PC reboots.
After that i remove ESET:SS and then my PC is normal again.
I have checked my logs in CMD-EVENTVWR but there is nothing there.

 

Might be stating the obvious here but was it running a scan at the time the CPU utilisation goes up?

 

Nope.
If i start the complete scan after installing it my PC is normal for 20-30 mins but after a while it's CPU usage will go up.
Whether i'm scanning or not.
Before i completely reinstalled my PC to get rid of crap and such the first thing i did was reinstall all drivers etc. which all we're and are installed.
Then i downloaded ESET:SS right away to provide my PC with optimal security but it seems ESET:SS just causes extreme CPU usage after a while which is pretty strange.
Here is a report of my PC it's specs according to EVEREST Ultimate which are all right.

Bump.

 

Does disabling real-time protection make a difference? If so, do you use default settings?

 

I'll try disabling that and use default settings.

 

This is odd....
When i try to install ESET:SS now it will install and finish the installation but it doesn't show up anywhere in my PC.

 

I reinstalled my PC.
ESET:SS is now set without disabling stuff etc. and it is no longer like charging a lot from my CPU after 2 hours etc.
And everything is fixed
