White pixel on screen

Hello Sumit,

I tried following your steps, however, the white pixel appeared again before I installed the display drivers. Also, no idea if this will help you but the white pixel is not there when I boot in safe mode. Any idea on what can be wrong?

 

White pixel in front of my screen?

I was playing a game one day, and when I clicked a button, it kicked me out of the game. I went in and out of the game trying to figure it out, and it turns out a white dot or pixel is on my screen. And when I click it in game, it takes me out of the game.
And because in the game the "pointer" (what you use to click things) is fixed on where the pixel is, I can't move or click without being kicked out of the game. Is there anyway to fix this?

 

Grey pixels

I have a brandnew laptop (Asus G750JX) and noticed a few grey pixels on my desktop, when I play a game I don't see them anymore. They appear only on a white background while browsing the web or checking email etc. What could cause this? It's not really annoying but it's there.
