The problem with the Geforce drivers

In short, on a fresh Windows 7 was installed driver 372,70. Today I wanted to upgrade to 378,49 but during the installation process the computer rebooted with the message of the BSOD error. In General, from the point Programs and features line installed the old driver is gone. New install can't but it is strange why the games run and work fine. Sobstvenno everything seen on the screen.
