This can have many reasons, first check the requiments of ur pc, if they match the games requiments. If all is ok and u fullfill the minimum check if ur drivers are all ok. Run > dxdiag > OK If theres an error, repair/reinstall the dmged driver. Or try to reinstall the game, maybe an other programm blocked some parts. If the problem still isnt solve, please give more informations about the error. To get them i can explain on Windows Vista OS ( Win7 should be same and Win XP similar) Go: Windows Start Symbol, then right mouse click on: Computer choose: Manage, now open the tree: Computermanagment>System>Event Display>Windows-Protocols>Applications search for the error that match with the time when the game collapsed.
