Frequent bsod memory management and sometimes something like ntfs.sys

looks like a memory issue to me, but there are more reliable programs out there than windows memory diagnostics, try this tutorial to test your ram

i will do it and get back with the results
thanks :)
but are you sure there is not any problem with anything else ?

There actually is another problem
You are running a Samsung Product ID on a Gigabyte board.
This makes your installation counterfeit.
Troubleshooting a counterfeit installation is useless as it is not known what has been modified to your system.
A counterfeit installation contains heavily modified code which causes the system to behave in unexpected ways.
For this reason, analyzing counterfeit systems is unreliable and most analysts won't try it.

Code:

OS Configuration:          Standalone Workstation
OS Build Type:             Multiprocessor Free
Registered Owner:          xxxx
Registered Organization:   
Product ID:                00426-OEM-8992662-00015 <-- Samsung PID on Gigabyte board
Original Install Date:     21-May-14, 4:02:08 AM
System Boot Time:          02-Nov-15, 3:08:46 PM
System Manufacturer:       Gigabyte Technology Co., Ltd.

I recommend to install a genuine copy of Windows.
