edited due to wrong spellingIMHO it cannot be a temp problem, at least not one connected with youz CPU. Systems with Pentium 4 processors will not shut down, when the processor overheats. P4s are designed to reduce speed hertz by hertz untill the processor has reached a reasonable temp. again. This is in order not to loose data, which would certainly happen, if the system just shuts down.However, I do not know, how an overheated graphics card will react.BTW my P4 2,4 Mhz generally heats up to around 65

I agree with the P4 heating - it should trottle down when it's getting hot.The side effect is that in a closed cabinet, it could cause overheating of other components like the videocard. So to troubleshoot you need to establish a good ventilation of the cabinet.:)

GabrielI've seen these exact symptoms occur from overclocking even when there were no signs of excessive heat. Even though you aren't overclocking you could try dropping your CPU and memory speeds and see what happens. By the way I have my P4c CPU overclocked 30% at higher than stock voltage and nevet hit 50 deg C, so I would be concerned about your temps.David

Hi guys.I Installed the Temperature and Voltage monitors yesterday and set up my CTD Flight while logging the Temps these are my figures:Just after turning comp on:Voltages stable.CPU Temperatures: 33CMoBo Temperatures: 32CAmbient Temperature: 20CI started a low resource consumming application and the temps rised to:CPU 42CMoBo:36CAfter I started FS the temps rised very fastCPU 60CMoBo 57CVoltages remain stable during the entire session with a variation of +/- 0.003V from basal values.Now I have an issue with the cables, I need to fix that and allow more space for the CPU to receive Air.I will apply Temp Compound Today and repeat the same Test.I noticed that while on cruise with clear skies my FPS count drop as the Temps in the CPU rised:From 120FPS average on 45C to 36FPS on 60C this is using the default 737.Up until I tested there was no crash, unfortunately I could not complete the flight, since most of my CTDs start appearing after I have completed at least half of the flight.I have another question that I am going to pass to the Hardware forum also:The Bandwidth of my Video Card in my bios was default 64 Mb, I increased that value to the Video cards cappacity: 256Mb... would that give me any trouble?

"The Bandwidth of my Video Card in my bios was default 64 Mb, I increased that value to the Video cards cappacity: 256Mb... would that give me any trouble?"It's likely to be a problem; 64MB should be fine.David

Gabriel, There is another thing that you need to check, this is something that I have had happen to me. Do you know what kind of memory you have, meaning the manufacturers name? Also do you have one stick or two of memory? It is possible that you have a memory problem, I had this happen once where only FS crashed my system, nothing else did, and I went crazy trying to uncover the culprit. If you have two sticks of memory you may want to pull the second one out and run FS and see what happens, if FS crashes pull out the first memory stick and replace it with the second one and test it again. If the memory is the problem this should point out the problem. There are programs out there that test the memory for you but they do not always work properly, I had a bad stick that these programs said was fine so do not completely trust them. Hopefully getting your temps down will be the solution but if it isn't then you have something else to work from. Let me (us) know how things go and if you need more help just hollar. I do this kind of stuff for a living so I'll help as much as I can. My email is [email protected] care,Philip Olsonhttp://www.precisionmanuals.com/images/forum/supporter.jpg
