whenever I play a mission game, XWA crashes to desktop with no error, or just reboots the computer. I'm running WIN 98 SE, 650 Mhz, 384 MB of ram.
What I can tell you for certain is that this is not some OS conflict. XWA runs smoothly with Win98 SE.
What version of DirectX do you have running ?
What VGA are you using ?
I'm running DX 8.0, no problems found on dxdiag, and i have an intel graphics card 16 megs w/ agp port
