Well, it looks like my ATI x800GT (PowerColor) PCI-Express card has crashed my computer (8E,C05). Since I removed the card and ATI drivers and re-install the Geforce 7300LE my computer has not crashed but the video response is sh.t (have not even tried to run Realflight 3.5).

I just ordered an nVidia Geforce 8600GT card. I couldn't pass up the price and besides Realflight 3.5 do not need heavy-duty graphics capability. I'm hoping I will get some other value-added from this card since I'm running Windows Vista Ultimate and this card is 10X compliant out of the box.
