Lite version works but full alpha crases on startup

[Dalee 10]

Hi Folks

I was using Arma III Lite, had a lot of trouble getting it to start because it would crash on start up. Read the forums and it was pretty clear it was due tot he video card I had. So I bought a new card, GTX660TI and the lite version worked fine....

So took the next step and purchased the full alpha now that the game worked, and now I cant start the full alpha, it crashes on start up again. Lite still works though.

I have reviewed the forums for posts about this and have followed them, I do not have zone alarm, I have tried the recommended changes to the set launch options in properties and I still have the same issue.

I know some people have said underclock the video card, but that is over my head, I am not tech savy, just an old fart trying to work this all out. I therefore have no idea how to underclock it, if that will even work.

ANy help would be appreciated.
