Windows 7 will not detect my 8600m gt and I cannot install a driver

I had my 8600 working fine but I had to update drivers. So I uninstalled the current driver because I couldnt update. Now My comp wont even recognize the hardware so I am stuck in 800 x 600 and in device manager it says "Standard VGA Graphics Adapter" and it wont detect my 8600m gt.

What to do?

Ive downloaded the most current drivers from NVIDIA but it says no compatibel hardware was found and it cannot install. So I went into it manually and went: Update Driver Software -> Browse my comp -> let me pick from a list of device drivers on my comp (now here it only shows the "Standard VGA Graphics Adapeter") ->Have disk -> DISPLAY.DRIVER folder -> then it shows me a huge list of all available dirivers. the problem is there are at least 30 different 8600m gt ones to choose from. I tried a few and it said "The driver slected for this device does not support this version of windows"

did you ever try installing the old drivers? nvidia still has the old drivers on their site too.
make sure you're installing the correct drivers for your os x64 or x32.

What is the laptop model number that you are having?

Have you tried the driver from laptop manufacturer's website?
