There are two ways to install Nvidia drivers.
Step 1
- Plug your nvidia graphic card to your motherboard and switch your vga cable to the new graphic card vga port.
- Boot your pc, it should run properly till you got to windows desktop.
- (Make sure you have the correct driver for your graphic card or it won't install the drivers)
- Now go to where you download the graphic drivers (6200) and run it's exe. It should prompt you to install your graphic driver properly.
- Reboot once the installation is done.
- Your graphic card should run perfectly
Step 2 (Risky and maybe more confusing)
(You may need to create system restore point before trying this method)
- Do not plug in your graphic card just yet and boot your computer
- It should be booting till windows desktop.
- (from here you need to download Nvidia 6 series driver which was already extracted and should have [nv4_disp.inf] to do this manually)
- If you have one, proceed to Device Manager and double-click the icon under Display.
- Choose manual installation and select install by yourself and you should be prompt to a windows with list of drivers.
- Select Have Disk and direct it to where your correct driver is in. It should found [nv4_disp.inf] by default and select ok, it should list out all drivers in the installation.
- Now choose your correct drivers and install it. It may prompt you to another windows but just agree and install.
- Your display now may blank and you can't see anything to do any work. When this happen, just press power button to let it shut down.
- Then install your graphic card to your motherboard, switch your vga cable to new graphic vga port and boot.
- It should boot properly all the way to windows desktop...
