I have an Alienware 17 with 880m gpu with 3d 120hz display . Recently I had overheating issues and thus had to repasted the gpu. After repasting, windows is not able to run the gpu. Whenever I try booting into windows, it gets stuck and the display turns black. The only way to boot into windows is by disabling nvidia gpu in safe mode. I tried reinstalling drivers, bios and most other possibilities, but no sign of hope till now. Now my question is since my laptop has a 3d 120hz display, there isn't an Intel integrated graphics; Only a discrete nVidia gpu. How is the display able to work after disabling the nVidia gpu? A local serviceman said the gpu is dead but if so the display would have not been working. Graphics property shows that currently The Microsoft Basic display driver is running. Both device manager and BIOS detect the gpu as 880m. Also, when I try reinstalling the graphics driver afresh, the installer detects the gpu as compatible and installs but gets struck halfway through the installation after which the display goes blank.
