To Sim. pilots and any one who can help,

Every time I fly the DC-3 and start to adjust its avionics along with GPS, the plane freezes up in flight. But if I fly it with just GPS its Ok, and helps here in stopping these freezze ups?

I have upgraded my old computer to XP 2400 AMD, put in the only Viedo card the my motherboard would take a PCI 5200, 128 MB card and use 512 Ram.

Thanks JFG 123

So far just two planes do this DC-3 plane and the WACO biplane, which when I fly it form the outside of the cockpitt.
In my own attempts to fix this problem, I did note that  in the start up files it showed the old XP1800 ,so I went to BIOS setting and set it up to XP 2400 at about 1.9 gig.

Now I am wondering how the BIOS got changed or if I forgot to save the changes to the new setups. could this be my problem? I am going to test it out today.

Any more helps here?
