@vortextheory: Ram is 32GB. Mouse is Logitech G603(i have installed driver and the problem persist even when mouse is disabled/using trackpad)
@LaszloNagy: I have reinstalled windows(clean) without the dell drivers/software. The issue still stands strong :S
@EDDY RACHMAT: Installed the Dell Support assisst, but it did not solve the issue.
Talked with a company that works with computers and the guy behind the counter had no advice for me.. He said that the issue could be many sorts and that they could take a look at it, but he could not promise that they would find a solution. Therefore i want to try everything i can before i pay someone to check it with no guarantee for success.
But thanks to all of you for trying to help me
