Thank you for responding, the problem was surprisingly the RAM itself, I ran memtest86 and it returned errors, so I had to dispose it. 
Hi, I upgraded my Dell Inspiron 7570 with an 8GB RAM that was recommended on the Crucial website. So, I currently have (8+8) DDR4 SODIMM RAM's. BUT sometimes the laptop turns off unexpectedly with a BSOD(Blue Screen of Death). I can't point out what exactly is the issue. I've run tests through Support assist, other hardware are working just fine. I must mention that this usually happens when I'm browsing trough Brave and even Brave shows some error codes now and then, and all of this has occurred post upgrade.
