I have setup a dual-boot, and will try under fresh install of Windows XP x64 to rule out a hardware / graphics chipset issue. System will eventutally be replaced with a M4500 running Windows 7....but I really would like to get MA3 running!
I'm a bit confused about what you expect to happen?
What will you conclude if a fresh install of XP-SP3 on the same computer, instantly shuts down when MA3 starts?
What will you conclude if MA3 runs correctly on the same computer, but with a fresh install of XP-SP3?
In any case, please let us know the results of your test.
