Display stops but CPU still running

[Nived Gumpena]

My specs are
AMD FX-8350
cooler master hyper evo 212x
Nvidia GT610
Transcend 8gb 1333
seagate 160gb
WD passport 1 TB
As rock 970 Extreme 4
corsair vs 550

The pc stops displaying suddenly
all the fans and everything are still working
so when I've read about this on internet
when the computer turns off
and the num lock on the keyboard doesnt work
then there must be a problem in the IC's of the motherboard
Now the mother board is replaced under warranty
and i removed those 2 rams just incase if they were creating the problem

Now the pc stops again
and its just been 2 days since I got this new motherboard
is again stops while I use photoshop
and the num lock key doesnt work again
Can anyone please help me with a proper solution
Thanks in advance

Do you have the BSOD? Or does the PC freeze? or just no display?
