PC Not Preforming How It Should Be Why?

Hello all i recently went out and bought myself a new pc, (2nd hand)

And it has been becoming more and more evident that something is wrong,

The Specs Are As Follows (dont know the part name for a few)

16GB ddr3 Ram 2gb GT 640 AMD 3.6ghz processor 4 core Win 7 1TB HDD

So i download steam and download black ops 3 for pc with the menu running at a solid 5-17 fps in game reaching 3-45 fps cpu usage at 100% with stuttering at everything low at 50% render resolution

i honestly believe that its not ment to be like this my friend had a pc with

12gb ddr3 ram 560ti 1gb 3.4ghz 12 core win 10

and he was reaching solid 60 fps on mid-ultra

what should i do?

I have done:

reinstalled all drivers up to date reset the BIOS Unparked CPU Cores

and im really struggling to figure out why this is?

Please download MiniToolBox  , save it to your desktop and run it.
 
Checkmark the following checkboxes:
  List last 10 Event Viewer log

Click Go and paste the content into your next post.
 
Also...please Publish a Snapshot using Speccy,  taking care to post the link of the snapshot in your next post.

   Go to Piriform's website, and download the free version on the left.  Click Download from Piriform.com (the FileHippo link requires an extra click). Or if you want to use a portable version of Speccy (which doesn't require installation), click the builds page link and download the portable version. You will now be asked where you want to save the file. The best place to put it is the Desktop, as it will be easy to find later.

    After the file finishes downloading, you are ready to run Speccy. If you downloaded the installer, simply double-click on it and follow the prompts until installation is complete. If you downloaded the portable version, you will need to unzip it before use. Right-click the ZIP file and click Extract all. Click Next. Open up the extracted folder and double-click on Speccy.
 
     Once inside Speccy, it will look similar to this (with your computer's specifications, of course):
 


     Now, at the top, click File > Publish Snapshot.
