Hi there,I have recently brought a new hard drive and i have reformatted my system. However i noticed that my FSX starts to crash very often now. When in the past it never crashed at all. I'm using the same addons, using the same OS, using the same hardware(except for HD)..and i don't know where the problem is..I always play in windowed mode, since i know full screen crash more often. This generally happens when i try to open a menu(EX: right click to change view spots, go to options on my menu bar to start/close time acceleration etc...)I'm using windows XP SP3. and this have never happened to me before. So i don't think it have anything to do with addons. does anybody know where the problem might be?

Video drivers?

If antivirus is on during install stuff like that could probably ensue. Outdated GPU driver or new driver is cr*p.Did you fiddle with BIOS?OR something is getting hot, dust will settle very deep and invisibly in the heatsinks where they block cool air from fan. And that goes for the elements in your gpu-board as well.My 2 cents. Good luck!

Download and install this .dll if you don,t already have it....Just put it in your main(root) FSX folder...Might fix it...Worked for me..D/L it here:UIAutomationcore.dll

Since you use a prebuilt computer you might have an inadequate power supply. What PSU do you have?

Thanks for all the quick reply!@Jim, video driver is the newest nvidia driver, which is 195.62@crewecut. I had ESET antivirus, but i had it for a long time, and i never had any problem with it...Didn't do anything to BIOS, temperatures are all in the 40s. The system is perfectly cool.@BMG. I thought that thing is only for 64 bit vista and windows 7..? but i'll give it a try anyway(never have to use anything like that before), ty@Ulfb. I upgraded my PSU long time ago because of the graphic card upgrade. I have a 650W Ocz PSU and it's more than enough to handle what i have. And i do not experience any problems with other games.

ok i'll try that.I just have to put it in right? I don't have to add it to dll.xml or anything like that? Cuz i didn't see any window that ask me if i want to run it or not.

Yes, just drop it in.

i just finished a flight, and it appears to be working fine. Hopefully it will stay that wayThanks for that file!
