NVIDIA DISPLAY DRIVER crash when Window 7 or Window XP upgraded to Window 8 or 8.1
And this error you get because the display driver is not compactable with window 8 or 8.1.Now you can download the exact version of display driver from my site.
Window haven't provided the option to use your hard disk driver freely.One option is left to use developer software which will provide you all access of hard disk with out have any loss in data
