Hi all Got my new computer working great with FSX showing good performance & FS9 even better. Have a problem when changing between the two, the computer hangs requiring a power off and restart. I ran filemon and it always fails at a different position normally loading aircraft or scenery in both. If I restart it will load OK on the second or third try. Once FS9 has loaded OK it will load every time but then changing to FSX it will hang again and needs two or more cold starts. System XP home with all updates FS9 with updates FSX with updates 6800 extreme chip foxconn 975X7AB board 8800 GTX 2meg ram VP2030B screen SATA RAID Onboard sound

I have XP, FS9 and FSX all on the same hard-drive but don't experience this phenomenom. I also have similar hardware:X6800, EVGA 680i MB, 2GB OCZ PC2-8000, 2 x 8800GTX. Although the MB is a completely different chipset.It sounds very much like a Memory problem. I'm not sure when you close FS how much it purges the memory. It certainly seems to load things much qiucker on the second and subsequent start of FS..which seems to indicate that there is some kind of memory buffering taking place. This is speculation of course but I suspect that when you close FS9 and start FSX it somehow causes a memory addressing problem. Doesn't happen with my 680i chipset though so can't really assist beyond suggesting a probable cause.RegardsJim

I would also check my RAID drivers and update them if possible. Loading FSX is a pretty intense application for a disk drive. With the quality of packed in RAID software for desktops, I'd be suspicious. Can you try it without the RAID?Does FS9 crash at all?I also have both, but don't really use fs9 all that often.Also:- Run Task Manager and see if there's another program competing with FSX during start up.- If you're overclocked, default back to normal settings and test.- Delete FSX.cfg and have FSX recreate it automatically.- If you're loading a flight directly, try loading into the FSX GUI instead first.That's all I've got...Steve GravleyOff to have a meatball sub, even though curry sounds great, too.

Thanks for the ideas guys The system is all untweeked with the latest board & V card drivers and both sims only hang on load up, but this is the first for me with a raid setup. I don't fully understand raid but it was suggested by the builder. He did say that he had problems loading XP on because the drives were to fast and windows could not keep up and got software for the board to fix it. If its not to difficult I would like to try a no raid setup is it a big job to change back. Thanks Paul

If you know how to put in another drive and mirror it, you can copy your stuff to another disk and boot off of that. Before Windows loads, there should be a RAID screen that'll let you hit something like F12 to enter setup. Be very careful here, but take a look around and see if there's an option to mirror a drive there. Or you could use Ghost, too...Or ask the guy who set it up.There are a few different types of RAID, some of which you could just unplug the other drive and it would work, but most desktops don't do this instead opting for speed instead of redundancy.

Did some more checking the raid drivers are over 7 months old, can I get updated drivers from Foxconn. I will try some more with raid and if I can't fix it go back to single drive. Thanks for the help Paul
