It looks like Shockware is right. I pulled the HD5770 ATI card and replaced it with a EVGA Geforce 9800GT and now I can run FSX without crashes in Win 7 64 bit. I have made no tweaks to anything but I think I will get nHancer and follow NickN's tweaking recommendations so I can increase the scenery details.Has anyone tried the latest Nvidia 197.13 drivers? I hate to change anything since FSX is working now and that is what I built this new computer specifically for.Thanks To All,Chas

I am new to this forum but not to MS Flight Sim. I have been flying with MS Flight Sim going back to FS98. I am currently using FSX. I have run Flight Sim on several different computers over the years. Trying to get maximum performance out of FSX SP2 I decided to build a new computer specifically to run it. It has been a nightmare. My new computer's configuration is:Gigabyte GA-X58A-UD7 motherboard BIOS F9Intel i7 920 processor No Overclock6GB Corsair dominator PC3-12800 1600mhz DDR3 core i7 memorySapphire Radeon HD 5770 1GB DDR5 graphics cardCoolermaster HAF 922 caseCoolermaster silent pro 1000W power supplyI tried first to run FSX under Win 7 64bit. The program installed correctly and ran. With no add-ons, when I start a flight it will run for a short time and then I get a black screen and the computer freezes. Sound continues for a short time after freeze then turns to a blatting continuous sound. Only way to recover is to reboot the computer, keyboard not responsive.I searched several FS forums online and found others had experianced the balck screen freeze when running in Win7 64bit so I wiped the hard drive aand installed WinXP SP3 then FSX, SP1 and SP2. When I run FSX I get the same black screen freezing that I got in Win7 64 bit. I have tried all the tweaks suggested by various forums and nothing works. I have reduced all the settings in FSX to bare minimums and still get the same result.Does anyone have any suggestions?
