    Hi,

    i have got something strange on my M17X R2. For those who don't know well this laptop , there is no igpu , just two mxm slot nothing else so no problem with PEG and stuff like that.

    Mine have an 7970m dell version, was working great till now. Sometime when i boot it up or when it go back from sleep the screen go black with red stripe , sometime green and blue too. I was thinking of defective gpu , so repaste -> nothing.

    It was appening sometime but i had just to reebot and that was good , no fps drop or artefact in game ... Uningine Valley benchmark was good ect .

    Today it was impossible to boot correctly, the computer was booting windows but the screen was black with red sripe. I had unmount the gpu, reflow it with heatgun and that was good. Was suspecting some bad memory chip.

    But the problem went back, so i have just tryed to plug in the tv screen to see if it was the gpu or mobo or laptop screen. At the same moment i was pluging the hdmi cable the screen went back on laptop , no problem run like hell ect ... Tryed to rebbot without the tv pluged in , boot with no probelm ...

    So i thinks that's not the gpu but the mxm slot who has some misscontact, my card do not stay at 45 ° when i am mounting it, it go flat directly, maybe with the heatsink its too heavy to stay in the air.

    What do you think about it ? I have made a lot of strees test, bench and game ( skyrim / bf4 ) and there was no artefact , no fps drop or anything , nothing more than usual with the 720qm i mean ...

    Grease or fluff could have done it. The mxm slot does have the video outputs going out on it.
