there's anyone can tell me how to change the graphic card?

simply put it in the graphics card into the graphics card slot in your motherboard, boot up your pc and then install the drivers

mmmm....does the card work without the drivers?

is it pc or labtop. I don't think you can change graphic cards on certain/if not all labtops. If its desktop take your back off and at the bottem should be the grahpic slots. then DONT FORGET TO INSTALL THE DISC.

Do you even know if it's compatible with your motherboard? If it is then all you do is slot it into a PCIx16 slot. Google it for pictures of whereabouts it goes.

yes it's compatible, i also know where is the slot .-.
i would know if i have to unistall old drivers and install new one before or after the card change...

Well, I'm not too sure because when I bought mine all I had to do was plug it in then use the Plug n' Play drivers untill I installed the official nVidia drivers. I'm pretty sure you don't need to uninstall the old display drivers.

Is your PSU strong enough?

Your graphic card probably uses two pci express connectors, so Before doing anything, make sure your psu has them.

Pci Express connectors:

Now you only have to insert the card in to the slot, plug in the connectors and screw it (with screws :rolleyes.


Next turn on Pc and if everything is ok donwload the latest drivers from the manufacturer. Never intall them from the cd, always outdated.

Hope that helps.
