I have been using geforce gt 210 1 gb. Now I want to remove it from my pc. But when I remove it my pc my pc changes into a low resolution mode. I am currently using amd a8 7600 processor. So how will I run my pc in normal mode after taking out the graphics card?? I was previously using amd a4 radeon 6320 hd graphics. My gigabyte motherboard model is GA-F2A68HM-S1.
