How to check if video graphics card is installed on motherboard or not?

I own a HP pavilion Dv3 Notebook. I have ATI RADEON HD 4550 installed in the notebook. I want to remove it and install nVidia GeForce 9500 GT in the notebook. So i want to check if ATI video card is installed in the motherboard or not. Please help as i need to change the card urgently.



Thanks in advance :)|||Your video chipset is not replaceable. This is the case with all modern notebooks.



Notebooks don't use video "cards". They have a graphics processor chip integrated into the motherboard. There is no slot for you to install replacement graphics cards.



This was the case with older notebooks that used MXM slots, but they no longer exist.|||There are some MXM cards made

Mobility RADEON HD 4550 or GeForce 9500M GT are NOT made in MXM cards



The list of current MXM cards is very short and available mostly to manufacturers only

3 from Nvidia

GTX 260M

GTX 280M

GTS 160M type 3.0



3 from ATI

HD5870 3.0 Type B

Type II HD4650

Type II HD4570

You can find them on ebay for about $600 USD

And you must have a laptop motherboard with an MXM slot

You do not have an MXM slot

It makes a lot more sense to get a new laptop



*The GTX 480m is now made on an MXM card also
