Flickering and pixelated screen

I've had my new MacBook Pro for about a week now, already the screen has started flickering. Today the whole screen became all pixelated and glitchy to the point that I couldn't see the mouse cursor moving. I reset the MacBook and now it's still flickering. I'm taking it in to be repaired on Friday the 2nd as this was the earliest time I could book it in.

It ***** when you spend a lot of money on new gear and it doesn't work.

This is my first Apple computer, I thought Apple had this kinda stuff under control. . .

I've owned several computers in my life and none of them have ever had hardware issues. . .

I guess I was unlucky.

Anyone else had this problem or know of a fix? I'm guessing it's hardware, but maybe its a software problem?
Cheers
