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?

Such freezes on a freshly installed FSX (without any other add-on) could be a sign of inherent instability of your system.It could be a heat issue that manifests itself only after some time running the sim.It could be the Graphics drivers or the Sound Drivers.You might as well check that you have the memory timings set correctly in BIOS. Usually AUTO makes life easierPersonally, i would proceed as follows.Disconnect all devices except the keyboard, monitor and mouse.Disable all non-necessary devices in BIOS. Notably sound device, and network device.Run FSX for an hour or so to see if it's stable.If it freezes, look at Graphics drivers.If OK, re-enable the sound device.Run FSX again. If it freezes you know it's either the sound driver or the device itself.Re-enable network device, and test again.If everything OK, reconnect USB devices one by one, making sure you perform a test before plugging the next one.I can tell you for sure it's not a Windows 7 problem. Moving back to XP is a step back.XP was excellent until SP2. Since everyone on the net was raving about how good XP performed versus Win 7. You know what the Redmond guys did after that? Yes SP3.If you were in Charge of Windows, would you really do your best to make an outdated platform beat your most recent jewel?I don't buy that. Anyone using XP should stay on SP2. :-))Gerald R.

First slap W7 back on it for sure, probably a video card driver problem, or sound but you could have some bad Ram, try running memtest http://www.memtest.org/ it has helped me detect faulty ram in the past. Also if you built the machine, just go back and double check everything inside the case, make sure everything is seated properly.

I have a similar problem and it is driving me crazy.FSX freezes up, usually when I start my decent on a long haul flight, eg. 3000nm, or 200 - 300nm from destination!!My flight consists of me taking off, enabling autopilot, turn on 16x compression. When 300nm from destination I change time compression to normal and start my descent and BANG - freezes and crashes to desktop. So annoying. :( If I do a short flight, like a take off and a couple of touch and go's or a flight from Dublin to Gatwick, it's fine.FSX installed on it's own HDD - 400GB Samsung (has about 300GB of free space)Can anyone help?My setup is:Intel QX6700 2.66Ghz @ 3.2Ghz on air4GB Kingston Hyper X 800Mhz (Running @ 667Mhz - don't know why!)ATI HD4870 1GB DDR5Creative Labs X-fi Xtreme Music 5.1Win 7 x64

Yep, I and many others have the same problem, all these ideas to solve this problem are just a hunt and peck search as I have tried one and what I got was I lost all my settings for my yoke and throttle system , I have notified Computer Pilot magazine about it, It might help there business to find out the answere, as who is going to buy anymore add-ons if you cant use them? But until the hamsters start turning the run-a-bout in the CPU, I think that the only thing to do is to uninstall one at a time all the add-ons until you find the culprit
