I have input lag and jittery mouse movement, I have changed all pc parts except GPU and PSU. Clean installed win 10, updated bios, installed latest drivers. Communities figured it out as my self that this is not software issue. Turning off the psu and turning it on makes the movement smoother for a couple of minutes, while installing/deleting programs the mouse movement speeds up. The temps are good for all components. What could be the cause and how to trace it? I appreciate the help!
