Problem installing drivers for NVIDIA Geforce GT 420

Hi!
When i try to install new update for my driver, it starts normally but when it's trying to install graphic adapter, it stops and says "installation failed".
This is first time I'm trying to update my drivers, and I have selected right installer from NVIDIA homepage. Anybody know what's wrong ?
Ty in advance

 

Did you uninstall the existing drivers? What is your OS and is it 32bit or 64bit?

 

Oh sorry for lack of information, I have tried that i uninstall existing drivers and my OS is windows 7 and 64bit

 

In place of using update. download the driver from here http://www.nvidia.com/object/win7-winvista-64bit-295.73-whql-driver.html and install.
This is the latest driver for your card.

 

Hope there is enough information

 

Hi my friend , you must use this tool

cleanning up all vga driver's leftover ( run in normal mode even safe mode ) , afterwards you will be able to have a good installation progress !! :wave

 

^ Didn't work ty anyway!

 

This is a new driver from Nvidia and some people have reported problems.

See this thread about Providing Driver Feedback:

What driver are you currently using? I would recommend the 285 if yours is older. If it is 285, stick with it until they work the bugs out of the 295.

In addition to that , you could give us the hardware id :

Start - Run type this mmc devmgmt.msc - Ok - right click to yellow device - Properties - Details - scroll down the arrow finding Hardware ids - there is a code in the box , we need it ( select all - copy - paste ) the code here !! :wave

 

Hope you mean my geforce gt 420 hardware id with "yellow device"
Anyway hardware Id:

PCI\VEN_10DE&DEV_0DE2&SUBSYS_2162174B&REV_A1
PCI\VEN_10DE&DEV_0DE2&SUBSYS_2162174B
PCI\VEN_10DE&DEV_0DE2&CC_030000
PCI\VEN_10DE&DEV_0DE2&CC_0300

And my current version is 275.33

 

Is there any other yellow mark in Device Manager except for this ? Download this driver

save it to desktop , you must try manually installation

do it !! :wave

 

Didn't work it just tells me "installation failed" nothing else. And i don't have anything yellow in my device manager

 

Do you restart your machine after installation completed ? You must go in to Device Manager to uninstall device ( vga )

reboot your machine , navigate to file destination and run executive file !! :wave

 

It didn't work either, did everything twice as you said and rebooted my computer. I wonder wth is wrong with my computer

 

Read tgell's post , be patient , trying this process again !! :wave
