Windows 7 RC1 Display Drivers for Dell Inspiron 1150
If you are still using Dell Inspiron 1150 which is having unsupported chipset for Windows 7 you must have faced display drivers issue. When you install Windows 7 beta or Windows 7 RC1 it will take you back to 1990s in terms of screen resolution.
Here is the solution:
1) Download the drivers from this link.
2) Restart the laptop in safe mode
3) Unrar the drivers in a folder
4) Install the drivers using Device Manager (Shortcut: Windows Key + Break -> Device Manager)
5) Restart
And you are done!
You are back to your old 1024x768 resolution.
Special thanks to my friend and colleague Kuntal for helping me find this.
