Ron,I'm not sure if you know this already. The AGP version of nVidia 6XXX series need to have extra power plugged in. There's a molex connector socket on the card which needs power from the motherboard.All you card crashes failures are consistent with what happens if the card does not get enough power.Keith

Keith,Thanks for post.Indeed, I had realised that molex had to be connected, and this I did! An odd bright spark of intuition from me. Fan needs power, where is power connector!(lol)It all seems to be working now, after a complete re-install of Fs9.Still getting segment flashing at high scenery airports, odd pause on ground, but I think sound is issue here, but thankfully no more crashes to desktop. So Far.Plenty of crashes on approach with my 737, just had one in atrocious weather approaching my home airfield of Glasgow. What you get when you cut inside ILS approach to land on time to please moaning passengers in Fs Passengers. Well they moan no more, I killed them!(g)
