Hi, I recently bought an ASUS M2NPV motherboard that has an onboard nvidia geforce 6150 gpu graphics card...... Since then I have bought an Nvidia geforce 7300 GS graphics card. I have installed it and loaded the drivers provided with the disk but I think my computer is still using the old onboard graphics card! Can anyone please help me!!! I need to know how to change over so my PC starts using the new graphics card? Many thanks to whoever can help!!!!
