Spellcheck man, spellcheck.

Proceed like this.

1) Download (but do not install yet) the latest ATI drivers
2) Un-Install the old nVidia drivers
3) Turn off the system and swap the GPUs. Make sure and plug the PCIe power plugs into the new 4870
4) Boot into windows and install the ATI drivers
5) Reboot when prompted and enjoy your new card.

If you are saying that your machine will not boot with the 4870 already installed (sorry, could not tell by reading), post your full system specs including any overclocks and your PSUs brand, wattage and +12v amperage.

I have xps 710 intel core 2 duo e 6700 2.66 4 gb ram and 750 W Power, When I place the new ati screen go black, when I switch on monitor its says no imput signal. I would have to try installing new drives with out monitor

as well when I use my old 8600 I can only have screen on 640 by 480 resolution and 4 bit color

@ Morfinel: Have you connected BOTH 6-pin leads to the ATI card? It must have both connected to work. If your PSU has only one there should be a molex/PCI-E converter in the box the card came in.
If you have uninstalled the Nvidia drivers the 8600 will only display 640x480x4bit because that is the default `emergency`display of Windows itself and you have done nothing wrong.

I have updated Bios. Connected new ati 4870 to both pci-e slots, I always connect 6 pin x2 leads and there is still no output to monitor I have contacted ati and they said to update bios and try other pci-e slot, monitor still don't work. I had 640x480 because I have geforce in sli and when I was trying 4870 then I connected only 1, would uninstalling geforce drives would change any thing ??
