Laptop Screen Flashing

[Sniggeh]

Lenovo Y400, i5-3230M @2.6 Ghz, Nvidia Geforce GT 750M, 8 gb ram, Windows 8 64bit, 1tb 5400 rpm hard drive.

I've only had this laptop for nearly two weeks, but already has an issue. I've been doing some gaming (Just Cause 2, Borderlands 2, G-Mod) and within the past couple days the screen has been flashing these random green and red stripes. It's been getting more and more frequent the more I game. Computer has been getting hot whenever I play, the cooling isn't too great. You can see the flashing here: http://youtu.be/pf1pgOUCDoI

Any suggestions? It keeps happening more and more

Well, it also happens in general browsing, right after it starts up, and whenever its cool.

Just updated drivers, still doing it.
