You don't say how long before the first crash occurs?
Do you always get into the game or does it happen on start up?
Is there any activity you are doing when they happen?
After the first one, does the second one happen faster or slower?
If you change the settings doe sit have any effect?
Does it Crash right to desktop?
Or does it just lock up?
If to desktop, does it lock the desktop as well?
If so do you need to do a hard reboot?
Or will a soft reboot do?
Do you get any kind of error message?
What does the event log say?
What is your system specs?
What are your drivers?
What are your settings?
Do I need to go on ?
Since the vast majority of people including me, have no trouble with the game, it has to be something in your setup or system, if you supply information instead of anger, I can help.
