FSX freezes system completely.If I go on an extended flight or a few short ones FSX will freeze my system completely."Ctrl-Alt-Delete" will not get me out either, my only option is the reboot button.Sometimes it happens during the flight randomly.I paused the flight once and came back an hour later and the system was frozen.It has happened a bunch of times switching back from the map screen, blank screen and frozen.Last night I finished a flight, presses "Esc" to exit, the selected "End Flight" and poof, blank sceen and frozen again.The worst part is the event view does not register an error, the only thing mentioned is the unexpected reboot.Very tough to diagnose without any clues!!FSX Acceleration.Everything should be up to date.Intel Core 2 Quad Q9550 Quad-CoreASUS P5N-D NVIDIA 750iCorsair 8GB (4x2GB) DDR2 1066MHzSeagate 2TB (4x500GB) SATA HDD2 x NVIDIA GeForce 9800GTX+ (SLI)Pioneer 20X DVD-writer SATACreative Sound Blaster AudigyMatrox TripleHead2Go3 x Samsung 22"Track IR 4 ProSaitek X52 Pro & Rudder PedalsCH Products Yoke, Throttle Quadrant & PedalsAny ideas would be appreciated!

Hi what operating system and any recent changes?

Sorry, I thought I included that :(Windows 7 Ultimate 64 BitOnly recent changes would be using FSX Booster from FSPS, which has very regular (almost daily) updates which I have been installing.

I think I have sorted out my freeze problem, might be related to my FSX Booster settings.I moved my FSX.CFG and restarted FSX. After an almost 2 hour test flight with the unaltered CFG file no problems yet.I'll have to test more to confirm.

HelloI had exactly the same problems, these are not the addons. The problem is Windwon 7 64 bit.I have it solved now witth the follow steps I have all the *. dll files released at the user level (FSX and FSX addons) with read and write permission.In addition, I have installed some addons on the second PC and let communicate over the network with the FSX. (FSMap, EFB, etc.)Please excuse my bad English, best regards and greetings from switzerlandRuedi

If the issue returns try adding this to your fsx cfg file: [GRAPHICS]HIGHMEMFIX=1Also add the Uiautomation dll to your FSX root folder.http://www.search-dll.com/download/1744.html
