I've been trying to install my new geforce 8400gs graphic card but as soon as i turn on the computer it freezes and won't let me run the disc or do anything. It works fine when i remove the card but the built in card isn't enough to play games on. not sure what to do next please help.
You probably need to disable the on-board graphics in the BIOS.
Or maybe set the new card to boot first, depending on what the options are in the BIOS.
thanks for reply, it is a pci express card, i've disabled the onboard card and everything worked fine for about half hour then it froze again. once it happened once it kept happening every 10 minutes.
