hmmm you sure there is no external power necassary for the 2600 XT I have the 2600 Pro and it needs a 2x3 power plug. Thats all i can think of, make sure the onboard
gfx are up to date. And try turning off the pc unplugging it and removing the
ram the put the
ram back in and hook it all bakc up, then try it. Other than that all I can think of is a shot card or your motherboard doesnt support the card.
See, this is your card. take a look in the upper right corner of it

I still think it needs 2x3 power.
