You don't need GPU driver to put PC to sleep.

goto: Control Panel\All Control Panel Items\Power Options
and schedule your PC to go to sleep.

this should tell us if GPU driver is to blame or not.
I can't choose sleep, but hibernate is an option.
This is what happends when the PC returns from hibernate state.
