I've successfully managed to run MG on a laptop with worse specs than this netbook. Yours has a 64-bit cpu so that's better for a start than the laptop I was using. That is, nevertheless a weak netbook though so only expect to play non-multiplayer games on small maps with very little resources so that less units are produced.
As filux said, your netbook has more RAM than your cpu can address, so firstly I would look at reducing that to =<4GB RAM (Click
here for further details about your cpu). This could also fix various other bugs you may have encountered while you've used your netbook.
Next, I'd recommend install a system such as ubuntu 14.04, as that will come with decent drivers pre-installed + configured (the laptop I was using was running fedora 18 at the time, which worked). Windows intel/nvidia/amd driver-stuff is full of non-fixable bugs. If you don't want to install a linux distro onto your machine I would still recommend trying MG on windows with =< 4GB RAM
When you load up Megaglest set everything to the lowest setting in video settings (even the resolution if you find this is required to make the game playable!). Try to start the tutorial again.
