The nVidia release notes advise that you do not roll-back graphics drivers but uninstall and then install the older driver:
"Do not Use Windows Rollback for Graphics Drivers To reinstall a previous or older NVIDIA graphics driver, do not use the Windows rollback feature. This method will not reliably restore all the previous driver files. Instead, use the Windows Add and Remove programs to remove the current driver, and then install the older driver using setup.exe."
Which version of Windows are you using? 310.90 only supports Vista, 7 and 8.
