I had the exact same problem, i tried many things to fix it, and finally, it was not "Update to the latest drivers" but downgrade to the driver that came with your card

Worked for me,can run just fine now, no freezing or d/c, but then again , might be different for each graphics card (Mine is Geforce 6600 btw) the driver that came with mine was 77.72 so if the one that came with your card doesn't work, try my driver (77.72)
Hope that helps

Ps .Don't for get to uninstall your current driver
