Thick red lines on NEW PC

Hello there!
I bought a new custom PC via DinoPC in the UK.
Here are the specs:
Intel Core i5 3470
Asus P8H61 MX USB3
Zalman Z11 Case
600W Zigmatec (Don't know if I spelt it right)
8GB Corsair 1333mhz Ram

I got it 3 days ago, so it is really new.It worked fine until yesterday, when thick, red lines appeared on the screen. My dad got angry and said how "Dell is reliable"
He is going to return it and get a overpriced dell. I need some help, quick. I have tried going on safe mode and uninstalling the drivers, but to no avail.
A post said if the lines are on the BIOS menu, the graphics card is dying, which it is ( ASUS EZ mode).
This rig is definitely new, and I am getting some pretty good temps. I have played The Witcher 1 and Elder Scrolls: Oblivion, so no stress.

If the rig is not fixed in time, can someone at least tell me a good company to buy pcs off of that are NOT custom build ( AilenWare , sadly). I don't think I can persuade him to buy a new custom PC.

All help will be appreciated,

  1. Sounds like a Graphics card problem.
    Order a replacement 7870, and then slap it in.
    Dell is far from reliable, never to listen to parentals talking about computers, most of the time they don't know what they are talking about.
    Its perfectly fine, call the company and report a graphics card issue, but before you do that, try different monitors.
  2. Remove the Radeon and use the on-board integrated video? Do the lines go away? If not, the display (or display cable) is the problem. If the lines go away, it may just be the Radeon. Verify that all connections are secure.

    Also, are you overclocking the Radeon. If so, stop and revert to stock speeds.
  3. Hi :)

    If the lines are in ONE PLACE all the time , its a failed screen...

    A picture would help me to tell you...

    All the best Brett :)
