I'am using Windows-7 Home Basic 64 Bit OS. My system has stopped coming out of sleep mode. i.e. if I manually do sleep from
shutdown menu, or
close the lid, or
sleep due to power plan, after re-opening the system, screen doesn't show anything. It remains blank. But everything works the way it should. i.e Hard-Disk, OS keeps running and I can shutdown also by pressing
Enter (in the blank).
I updated display drivers, Graphic drivers, Chipset drivers to the latest version. What could it be? (corrupt hibernate file?)
