    Nvidia GT540M switch problem with Intel HD integrated

    I've recently bought a notebook ASUS X53S I5 with 2gb GT540M.

    The problem is that my computer works with integrated INTEL HD video card and when I start a game or application, my GT540M starts to work. But when I play Wow, I got 2 sec freezing spikes. I think that the only reason could be the video card used so I need a way to "disactivate" completly the integrated Intel HD video card and use only GT540m.

    Any suggestion?

    P.S.

    I'm sure that is a hardware/software problem since from my desktop (older than my notebook, with ATI 5570 HD 1gb and only dual core CPU) I've no freezing spikes at all

    Are all your drivers up to date and does this spiking happen randomly or at specific moments (after alt-tabbing, when playing youtube movies, etc...)?

    I would check on the WoW Tech Support forum. This is a known issue with dual GPU setups on laptops, but I don't know of a work-around.
