I would not revert back to earlier versions. The latest 2 or 3 drivers are always the best, even for a GTX 460. The latest drivers have specific fixes and optimizations for games and fixes for GPU issues.

If you are getting a blue screen, it is likely due to your method of driver installation or a hardware problem. I would download the latest 314.07 WHQL driver from the Nvidia website, then do the cleanest install you possibly can. You could just install the drivers and tick off the "Perform a clean install" checkbox. Or, you could uninstall everything Nvidia manually through the Windows Control Panel, delete any Nvidia folders on your hard drive, restart, then install the new drivers using the Clean install mentioned earlier.
If you still have problems, check back and we can look at other issues that might be causing the problem (overclocking, power supply, defective components, etc.).
