Screen tearing

Greetings Posony.
I faced such a problem - without vertical synchronization + triple buffering, the wildest stripes go across the screen. Such a problem is observed everywhere, for example, in bf4, daing light, division and others.
The bottom line is that with the slightest drop in FPS, even up to 50 causes strong lags. Friends do not have such a problem. Without synchronization, they have small stripes ~ a couple of centimeters. And my image twitches from all sides.
I shoveled a bunch of forums, looked at vidos, but nothing helped.
1.I changed the surge protector to an extension cord (It was recommended to insert the plug into an outlet without grounding)
2.Changed all the wires from the monik (to the outlet and in the VGA video)
3.In the nvidia panel, twisted the settings (I put adaptive synchronization, changed the screen hertzon to 59Hz and 61Hz and others)
4.I put the aero style in Windows, on the advice of one student (Although he was standing)

Guys, help solve the problem :)
