    Hi everyone here's my my problem and i need your expérience(sorry for my english i'm just french...) :
    I own an Alienware M17X R2 and i have a trouble with my screen, start fine, Windows fine, but after few minutes screen start to blink and then the screen is green, blue, red, (RGB)
    I've plug on another screen to test if the trouble is from GPU, everything work fine on another screen but laptop screen blink (RGB) constantly..

    I have an AMD Radeon 5870 HD mobility series
    I've change several time screen cables (bought on eBay) the problem is constant...
    I've repast CPU, GPU problem is constant
    The screen have an inverter inside

    So the question is how to diagnose the problem ?
    I have plan to buy another AMD 5870 and hope the problem is over.
    But if it not what can i do to solve it ?

    Thanks for your Time, thank for your help

    Seems like a possible faulty GPU. Have you tried changing it to see if behavior continues?
