How to fix Battlefield 3 crash to desktop?
If Battlefield 3 crashes to desktop when your playing then you should try to up the voltage core.
I have experience the problem on my Nvidia 560ti and when I changed my Core voltage from 987 to 1000 in MSI Afterburn then I was able to play Battlefield 3 without the crash to desktop.
Remember when you messes with the core voltage it is you own problem if you break your graphic card
