Zino,

Try uninstalling all Nvidia drivers, believe in Control Panel Add/Remove
Programs. At this point, you may like to check the hibernate/sleep function.
Then, following Nvidia's installation instructions, reinstall the drivers.

You also might want to check the power settings in Control Panel Hardware
and Sound Power Options. Make sure the options you want are set properly.
