I have just about had enough of CDT's. Almost all my flight end suddenly in a CDT or a frozen computer. I have removed duplicate textures, scenery errors, duplicate AFCAD's, defraged memory and hard drives, bought "Ultimate Trouble Shooter" and removed as many resident programs that can sensibly be done. I have also cleaned up my registry with "Registry Healer" and incorported all the "tweeks" I can find in the posts in this forum. Still CTD's so I re-installed FS9 in a separate partition - a brand new install. I removed all traces of FS9 on any drive prior to the re-install.First flight in the default cessna from Seattle and sudenly a black screen and frozen! Nothing has been added or changed. I run Windows XP Professional with service pack 2 on a AMD 64 Processor 3000+ with 1024MB RAM with graphics NVIDA GeForce FX 5900 Ultra with 256 RAM. I am at a loss as what to do now. Any suggestions or should i just give up?

What causes these errors.. (i.e. when its a CTD and it asks to restart FS2004, what is the dll involved?)..I have just sorted out what I thought was a never ending problem but was caused simply by two different memory clashing together even though no problems are reported in any other games or applications!! Read my thread: http://forums.avsim.net/dcboard.php?az=sho..._id=13438&page=and tell me if any of what I had problem with is what you are experiencing...

Thanks I will work through the suggestions. Sorry for the CDT's I obviously meant CTD's - too late now

No problem! I Just hope that I was of help :( :D

Did you install the fs9.1 patch?If not did you disable the autogen.xml in the FS9 folder?CTD's were a known issue pre 9.1 due to the autogen. I still left it disabled after the 9.1 patch anyway just to be safe!Glenn

Yes I did. I think I may have found the problem and thanks for the input. It may be my power supply. Reading through the posts the power supply was mentioned and I ran a program called BCM Health Monitor and it shows all the voltages out of limits. I checked the supply and find it is only 300watts, which in the posts suggest might be too low for the graphics card I have. All other systems checked out OK. I will now go and talk with my IT person and get some more advice. There may also be some problems with he cooling fans even though in the BIOS the alarms are not activated and show the temp to be normal (BCM says the fans are running too slow). I again thank you for your post and subsequent threads. If I cannot solve the problem I cannot fly as CTD are all too prevalent.
