You may have heard that this is a simple plug-and-play operation, the truth is that it is not quite so but still, it isn’t complicated either.

Graphics cards are plug-and-play to a degree, you need to plug them in the PCI Express slot, connect the power cable if needed, and connect the monitor, at this point, you will have an image on your display, and the OS will recognize the graphics card and install generic drivers for it.

If there is no other graphics card installed on your PC you can plug in the graphics card in the PCI Express slot on your motherboard, afterward you need to screw in the screw that secures the graphics card to the case and connect the power connector from your PCs power supply.

Don’t forget the screw your graphics card to the case, many people skip this step but if you don’t do it you can by accident pull the HDMI cable the graphics card will move and this will add tension to the PCI Express slot, in many cases, you will get away with it but you can be one-off the more unlucky ones and damage the slot. I’ve seen it happen more than once!

Now you need to connect your monitor to the HDMI output and you will have an image on the screen, the operating system will install generic drivers for your graphics card and this will make it usable just for very basic tasks like outputting an image to the display.

Can I Swap Out My Graphics Card?

Before you swap your graphics card you need to unscrew the screw that holds the old graphics card secured to the PC case and release the clamp that blocks the graphics card in the PCI Express slot. Now you can pull the old graphics card and plug in the new one without any complications.

And don’t forget to unplug the power cable from the old graphics card, swapping graphics cards is a simple operation but many newbies get in trouble because they rush and don’t push down the clamp of the PCI Express slot and end up damaging it.

Before you swap graphics cards you need to uninstall the old graphics card drivers, don’t worry you will still have an image on the display because your operating system will use a generic driver.

After you make the swap and plug in the new graphics card make sure to install the drivers for it and you are good to go.

Can a Graphics Card Run Without Drivers?

A graphics card can run without you installing drivers because the operating system will install a generic driver that will make it possible to output an image on the display, this is meant to be a temporary solution and not a permanent one because your GPU performances are highly reduced.

Practically if you don’t install the graphics card drivers you will not be able to enjoy using the more graphically demanding software like games, video editing software, etc.

Do I Need To Uninstall Drivers Before Installing The New GPU?

The best practice is to uninstall the old graphics card drivers before you change the cards, the new graphics card driver may have conflicts with the old one and you will end up with a lot of problems.

If you upgrade from an old NVIDIA card to a new NVIDIA card that is from the same family, the new card will work fine with the old card drivers because they all come bundled together and the cards are very similar, but still, sometimes this can cause problems. It is better to uninstall the drivers and then make the card swap, afterword you install the new drivers.

It is always better to be safe than sorry. Always the better solution is to uninstall the drivers before a graphics card upgrade than to troubleshoot future problems.


By now I hope you know that graphics cards are not plugged and play but are very close to being, you just need to remove the old drivers and install the new ones and you will be good to go.

Upgrading your graphics card is a simple process and you don’t need to worry about it.
