hi everyone. I just installed a geforce 8400gs which i installed on my computer. I know it's crap, I bought it before I knew anything about graphics cards. Anyway my pc has geforce 6150se onboard graphics, and I can't disable it. I have went in my BIOS and set display settings to pci, didn't work. I went into device manager and disabled the 6150 but it just reboots my pc saying the pci display adapter will not work. Does anyone know of a solution to my problem?
