Hi,

Just in case anyone has the same problem with crashes, this is what I did.......

I have a Gigabyte GTX 560 Ti 1GB card. first I under-clocked the card from 900mhz to 800 mhz this seemed to be a quick fix

But today I updated the bios on my graphics card from the gigabyte website, once i did this i bought my GPU speeds back up to stock levels ie; 900mhz, I have been playing all night with no crashes so far.

Hope this helps if your having problems with crashes/freezes.
