Ok, slightly unusual problem here.
I have a Dell Inspiron 530S computer, running windows 7.
It used to have Windows Vista installed. While Windows Vista was installed, I manually installed a graphics card; something from the NVidea family I believe. This was a few years ago. I installed the drivers for it, and it worked fine.
I have recently formatted the primary harddrive and installed a clean and registered version of Windows 7, and now it can't find the graphics card; it using the hardware the came with the computer, Intel G33/G31. I've tried opening up the computer to find the NVidea graphics card, but cannot remember what it is supposed to look like.
So, what should I do? Is there a way to make Windows find and start using the NVidea graphics card, as opposed to the Intel G33/G31? The hardware should still be connected.
