I have an acer aspire x3200 which has Nvidia 9200 onboard graphics. As this was not good enough for me to play some of the more serious games coming out nowadays I decided to upgrade, and after buying a larger case and psu decided to buy a new graphic card (xfx Nvidia 9800 gtx+). I installed it into the pcix slot and checked the bios which says it is the primary display, but for some reason I cannot get it to bypass the onboard graphics. I have tried disabling the onboard graphics in the control panel but still it won't use the new graphics card. Is there anything else I need to do, or is it simply a case of a new motherboard? I am using vista with service pack 2, have an athlon x2 dual core processor, with 2 gb ram. please excuse me if i'm missing something really obvious but i'm quite new to computers.
