Did you install motherboard drivers?
Do you still need a hand?
What is the exact Make and model of computer and Operating system?
EDIT>>Did you get a Driver cd with your Dell?
You can use it or check Dell's website for updated drivers
Your video card may not be compatible with the newer Nvidia drivers
Is this the one you downloaded?

But here's a link to drivers and manual
