ok,

i´ve tested it for hours now laugh
even turning on the hardware singleway didn´t crash the game again
so in my case the bios was guilty, even if i´d been sure that i have updatet it when installing win 7 in febraury an update if it has been my solution so far

maybe it will help some of u - i hope most of u

i wish u good luck and if works certainly a lot of fun laugh
