I honestly believe I would have better results trying to find a breeding pair of unicorns than getting a result using FSX with multiple monitors!

My PC has twin gf8800GT 512 cards,(with 2x19" & 1x22" widescreen LCD monitors attached), 4GB ddr2 ram, Q6600 CPU, XFI xtreme gamer sound card and two 250gb HDD.

I have been trying to get FSX to run with a simple front, left & right view on the appropriate monitor, but it always crashes, locks up and have to do a hard reset.
The PC is up to date for service packs, drivers etc, as is FSX.

Anyone give me a few pointers please ?
