    Hi everyone

    I recently installed W7 Ultimate x64 and am dual booting alongside the original Vista Home Premium x32.

    With W7 my laptop screen flickers intermittently in that i get horizontal white lines which can appear anywhere on the screen. It is most frequent when scrolling a browser page. This flickering does not however happen when using an external monitor. Nor does it happen with Vista.

    I have tried various VGA drivers, all of which give the same problem.

    PC Specs:

    Acer Aspire 5920G
    NVIDIA Geforce 8600M GT
    3GB RAM
    Intel Core 2 Duo T7500 @ 2.2.GHz

    Thanks for any suggestions!
