Strange behavior from inspiron 15R 3521 Windows 8 touch screen display

Question

Ever since I got this notebook back from the repair depot, i've noticed some strange behavior from the touch screen aspect of the computer.  Everything else works fine on it.  I can boot into windows etc.  When I start to use my touch screen once in a while it will automatically start showing a bunch of dots on the screen as if I'm pressing down on the touch screen but I'm not.  Sometimes I cant swipe up to unlock the computer.  Sometimes the dots will show up in a straight line with more than just one and when I press the Window key, it brings me back to the tiles and just opens up any app.  My only way to restart the computer is by either taking the battery off or pressing the power button down.  Dell has already sent a technician to my home to replace the touch screen plus dell's tech support line but the problem is still there.  Could it be possible that a touch screen controller on the motherboard can cause this problem?  Is there anybody else who is experiencing this problem as well or had a similar problem in the past??  I've provided a photo as to what is happening w my touch screen.  AND I'M NOT EVEN TOUCHING IT!!!!!

Just an update, Dell is sending me another Laptop computer to replace this one. I should be receiving it tomorrow. I've managed to make the dots disappear a little bit by formatting my hardrive and re-installing Windows 8 from scratch. The dots still appear at random but not as much as before. Even before installing the 8.1 preview, I've noticed that the dots appeared during the end of the Win 8 setup where you pick a computer name, color etc. It might have something to do with the hardware which I'm completely unsure or a buggy driver that causes the dots to appear at random.

I also re-installed Windows 8 3-4+ times and it still messes up

yeah sure no problem will do. just couldn't do anything because I couldn't log in. If anybody is curious as to what is happening, I recorded a video of the problem with my iPhone. https://www.youtube.com/watch?v=vlgGuqDth4U It shows me turning on the laptop on/off and how the dots randomly appear and make the computer not functional.

This has been happening to my wife's new laptop.  We contacted Dell and they ran some diagnostics.  Seemed to be okay for a couple days, but now it's acting up again.  How'd you get a new laptop out of them?
