Black horizontal lines appearing across laptop screen

Took delivery of a brand new laptop yesterday with the following specs:

Unpacked it, started using it, only to find black horizontal lines appearing across the screen sporadically. I updated all drivers, downloaded and installed all Windows updates but to no avail. Screenshots:

First screenshot





Second screenshot





Third screenshot





Some points to note:

• I had the laptop connected to the TV screen and the lines appeared on
  the TV as well, thus suggesting it's not a screen issue.
  
• Because it's a sporadic and somewhat rare event, I can't say whether
  the lines appear during a particular operation/screen or
  anytime/anywhere.
  

I've done a bit of poking around on the net and found that usually the culprit is the graphics card, but not sure. Any suggestions?

 

horizontal pink and blue lines

I have horizontal pink and blue lines starting at the top of my touch screen at start up. The only way to "fix" the problem is to use the touchscreen and restart the computer. I can see a small portion of the desktop at the top of the screen and it appears
normal. Any suggestions?
