    Hi,

    I am fairly new to macs and I am having a problem, my Mac Pro keeps restarting. I had a quadro FX 4800 video card on it, but it apperently was useless for gaming ( had problems with all the games i tried), so i swapped it for a NVIDIA GeForce GT 120 .
    I was instructed that once the card was put in i would just have to start up the Mac and download the drivers.
    But every time i try to start up it just keeps teling me over and over the mac has to restart. Is there some way to fix this?

    Would having the Mac dual booted with Windows vista ultimate be a contributing fact to this problem, as that starts up but the display is weird and the graphics card doesnt seem to be registered on the system.

    As i said i am completely new to macs so any hints or help would be massivly apprecaited.

    The error message you're receiving is called a Kernel Panic. It has nothing to do with Vista.

    Remove the new graphics card and put the old one back in so you can boot the computer. Download the drivers for the new card, and re-install the new card.

    If you still receive the kernel panics, the new card may have been damaged. If it is advertised to work with a Mac Pro, you should be able to exchange the card.

    While handling the electronic components, please be electrically grounded! If you do not have an ESD wrist strap, please keep one hand on the metal chassis of the Mac Pro while you're removing and installing the cards.
