While flying the PMDG 737, my computer crashes. It freezes and my PC makes many loud annoying shrieking sounds. It usually happens about a half hour into the flight while I'm climbing through the 20K's. It didn't used to happen until the past few flights I've flown. I changed my video drivers, but that hasn't helped. I'm using the official 61.76 drivers on my GeForce 4 Ti 4400. Has anyone heard of, or had this kind of problem?Thanks,Tim

wots the rest of ur spec? and OS?

Sounds like it may be your CPU. If you can, download any software that lets you view your temperature settings on your motherboard. That load shreiking noise may be the noise by the motherboard saying your CPU has overheated (same thing mine does)Nick B.Continental Airlines 737NG Pilothttp://www.precisionmanuals.com/images/forum/800driver.jpg--AMD Athlon XP 3200+ @ 2.2 Ghz (Equal to 2.8 ghz)400W Power supply3x 80 mm Case FansSoyo VIA KT600 Dragon PlusnVidia GeForce FX 5200 128 mb2 x 512 PC400100 GB Western DigitalMicrosoft Sidewinder Precision 2

The rest of my specs:Athlon XP 3000+ (I don't know why it would be overheating...I'm using the fan that came with the retail package...currently running at 71C/159F) which does seem a little high now that I think about it.Windows XP HomeDirectX 9.0b1 gig RAM

Oh yeah that is high, under a full load my CPU temp never gets higher than 53C on my XP2500. You need to make sure that dust has not clogged up the airflow into your PC, even if it hasn't try to blow out as much dust as you can since you are looking at it anyway. Be sure to check closely the area around the CPU and it's fan and make sure that dust has not clogged up the heat disapation fins. Make sure that the CPU fan is running as it should, most temp monitors also show the CPU fan speed, check this out and make sure it is running correctly. Check any fans that bring air into and out of your case and make sure they are running as they should. Finally make sure that the various cables in your PC are not blocking the airflow around the CPU, this can often cause overheating. If everything checks out as it should you need to get more air into your case, buy another fan or two, the more airflow the better. One easy method of cooling would be to remove a side cover and have a room fan blow into your case, but if you use this method be sure to clean out the dust every once in a while. I use this method during the summer months just to make sure that if the air conditioning fails I don't get an overheat on my system. If you need any more help just yell and I'll be happy to help.Best Regards,Philip Olsonhttp://www.precisionmanuals.com/images/forum/supporter.jpg

Yes, I had this problem once a while back. I had the wrong Sound Blaster drivers installed for my Sound Blaster Live card.Go to your sound cards website and download the proper set of drivers and install. Floyd

Ok, approx. 76C is maximum operating temperature for that CPU.The fan supplied with it is really crap and useless when heavy load is put on the CPU nonetheless temperatures getting that high is still unlikely but could be caused by an improperly placed heatsink or slower operating fan.Anyways, I suggest you get a better heatsink fan for your CPU and if you cannot fit it yourself get someone who knows how to do it.AMD's run very hot, continuing to runyour CPU at such high temps will either kill it sometime soon or cut it's overall lifespan by half.Cheers,Terence

Ok, well I blew a lot of dust of the fan, and I also plugged in 2 case ans into the power supply that are now running. After a reboot, I'm now running at 53C. Could this solve my problem? I'll also try downloading the latest sound card drivers.ThanksTim

Tim, That may be enough to keep you out of trouble, hopefully. Now you can just test it by putting it under a load, that is run FS9, and see what happens. You might want to monitor your temps from time to time while you are flying just to see how high the temp actually goes. Post the results here and I can give you some more advice if it is needed. Terence is correct in that the standard fans that come with CPU's are usually not all that good so if you continue to have problems you may have to get a better CPU fan and install it. In my experience, I work on PC's for a living, the generic fans that are supplied with the CPU's are good enough for most people's set ups but in some circumstances when you run programs like FS9 that are very demanding, they fall a little short. See how things are running now since you cleaned it out and increased the airflow, you may be ok now, if not we'll see what else can be done for you.Take care,Philip Olsonhttp://www.precisionmanuals.com/images/forum/supporter.jpg

Anytime your AMD XP series CPU reaches about 155-160+ degrees you better believe it will freeze your system up. Those CPUS always run hot unless you have a very good fan installed on the CPU and this does not include the default one. I know because I have run XPs CPUS 1500 XP, 1600 XP, 1800 XP, 2100 XP, 2200 XP and they are all alike. In fact my 2100 XP was one reason that I am now running the 64 BIT which by the way does not ever get hot like the old AMDS. My old system actaully got so hot it burned ;D goood excuse for a upgrade though don't ya think?Best Wishes,[h4]Randy J.

buy Intel, no heating issues :DJust kidding :)bye

40c is the "possible overheating point" where there is a chance it can overheat and crash your system, and 81c is the internal fry point. Try buying a Socket A cooling fan with about 40+ cfm. Those Thermaltake Volcano's are good. Would also recommend buying some 80mm fans (if your case supports it) and putting some in there to circulate air. Have one in the front blowing in and one in the back as a exhaust fan.Nick B.Continental Airlines 737NG Pilothttp://www.precisionmanuals.com/images/forum/800driver.jpg--AMD Athlon XP 3200+ @ 2.2 Ghz (Equal to 2.8 ghz)400W Power supply3x 80 mm Case FansSoyo VIA KT600 Dragon PlusnVidia GeForce FX 5200 128 mb2 x 512 PC400100 GB Western DigitalMicrosoft Sidewinder Precision 2

I just finished a 737-800 flight, and I made it without the PC crashing. The CPU temp maxed out at 62C, but stayed mainl at 60C for the fight. I've had a LOT of bad luck when it comes to installing CPU's/fans. I'm extremely hesitant to undertake that job again. Will I be alright running at a max of 62C???Thanks,Tim

I'll tell you what helped me with that type of CPU. Do not put a lot of thermal goop, you only need enough to just cover the little core, any excess will just get into the other areas of the CPU housing and heatup. Another desparte measure that worked very well for me was to remove the side case panel. At times I even had a small fan blowing directly into the case and that really cooled it down too. Of course this will create a major dust annoyance but does work as a temporary heat quick fix.Best Wishes,[h4]Randy J.

Smith[/h4]I'm running an A64-3400+ and even with the stock HS/Fan I never see over 55c. I updated my BIOS and installed "Cool & Quiet" and my electric bill decreased afew bucks. Your right Randy, the A64 chips do run a lot cooler. That and the fact I can barely hear this thing running. It's the quietest most stable machine I have ever owned.Regards
