Put you old ram back in and your old video card back in, if you know what they were put your old video card drivers back in, if you do not know then use the 182.50 drivers. See if your problem goes away. If you want you can just put the old ram back in and test and if that does not work then put the old video card back in.If that fixes your problem put the ram back in and test, if that passes put the new video card back in and use the latest drivers available from Nvidia and test.Some people say that it is not necessary, but when changing Nvidia video drivers I always reboot and use driversweeper, only use this for video drivers, nothing else that shows up. After you run driversweeper reboot and install the new drivers that you want to use.I just thought of something else, if you are using XP 64b with Nvidia 257.XX drivers this can cause a crash in XP 64b, try the 182.50 drivers

Hi thanks for your reply I am using 32bit on my systemyes the drivers were changed outthanksIan Snow

HelloRegarding your RAM, go into your bios and load the defaults (Failsafe)Reboot , enter the bios and set the RAM timings to match your new RAM.your new 1gig strip matches your old RAM , right? if not all bets are off

Hi Ian,Did you by any chance delete the FSX.cfg after upgrading? If not delete the .cfg and restart FSX, it will rebuild it and FSX should run fine afterwards.Whenever I upgrade the nVidia driver, install the latest DirectX, add an addon or update I rebuild the FSX.cfg, make sure that you back the old one up and make a .txt file listing all the edits that you will need to paste into the .cfg, makes life really easy.Give that a try and see how things go.

good morning I did uninstall and reinstall the sim 3 times since the upgrade.and that did not fix the problemI also made sure all the folders were deleted alsois it possible my machine is not powerful enough to handles the new card?thanksIan Snow

Not powerful enough no way, 950W is way more than you need! Way more don't even worry there. All I can think of is try putting the old RAM back in and see if it works. If not try using an older Nvidia Driver.

you might be having a sound issue with the newer nvidia releasestry going back to the 197.75 release, plus nHancer still works with that version.
