Ok So I finally gave up and did a hard reset of my laptop, I even upgraded my RAM to 16 GB. The mouse lag issue is solved, but now my pc is taking a long time to startup, and sometimes when i restart i just get a blackscreen, I have to force shut down and then start up laptop again for it to work, It still takes a long time to startup, Im gonna try a clean boot again to see whats wrong. PS This time it must be some 3rd party app
