OverHeating????

Recommended Posts

Hi All, It has been suggested that my recent lock ups might be due to overheating. Can anyone give me advice on how to find out if this is the problem. If so where is the best place to get a new fan from for the UK Cheers Daren Windows xp Anthlon 1800xp 512 Ram 40gb hdd Geoforce 2 TI VX Onboard sound

Pretty simple -- take the case or side cover off your machine -- get a big deskfan and have it blow into the machine while running FS2002 and see if you get lockups -- I had an overheating problem with my ASUS Geforce2 MX video card which was causing lockups -- it has a heatsink but no "on-card" fan -- but the heatsink faces down so any heat that it was dissipating was rising back onto the card .. Force fanning like I suggested soon revealed that I had a heat problem -- so I bought a small PCI exhaust fan to suck the hot air off the card and expel it , plus I also installed a case intake fan at the front of the case -- now , here in sticky Brisbane Australia, where the temp in my computer room can be around 34C , I have no problem.Barry

Barry hit it exactly. Just follow his directions and you'll definitely know if it's the heat affecting you.

Barry has the answer for diagnosis, however IF you still have problems with your computer locking up, the very first thing I look at is the RAM!!!!!!Let me say that again. If a computer is locking up the very first thing I look at is RAM!!!! Did I say that clearly enough LOL ;)FS2k2 is the most RAM picky program on the planet. I have been a system builder for 12 years and barring anything else, FS is the most RAM picky.I have taken machines from customers who were having lock up problems and installed FS2k2 on the machine just to check it out and walla, during installation it will rear it's ugly head. You don't even have to fly a plane to check it!If your still having problems after you try the fan trick, let us know.-----------Wilson HinesHEAVY LHC EditorAOL IM: dal276whBush Flying Unlimited: SIXUVI014 "Heavy"http://avsim.com/hangar/air/bfu/logo70.gif

I can only agreeMy PC is filled with hardware, so at the moment I have 4 fans in the case, with 2 pulling in air, and 2 blowing it out in the back. I'll be adding 4 additional, once I get around start overclocking (might go for watercooling of the CPU then).

I concurr. Do exactly that. I also have the side off my box and a fan blowing inside. Works great - no more lockups. I spent a long time figuring that one out. :( Adam

Good one Flappy, check that out! If your running an Athlon I never install one in anything less than 300watts. AMD says 250 is ok, but that is not for systems with extra preriphials like burners and a ton of PCI cards, usually like us ;)-----------Wilson HinesHEAVY LHC EditorAOL IM: dal276whBush Flying Unlimited: SIXUVI014 "Heavy"http://avsim.com/hangar/air/bfu/logo70.gif

Guys Guys Guys!!!!Talk about support. Great!!!!!!!Right this is where i'm at!As you have already read i have a Geoforce 2 TI VX which of course has a built in fan unit. I have been to the PC store and picked up a fan for the case and installed that! Nice fresh breeze now accros the cards. i have also seperated the the Modem and usb card away from the video card to give it "Space to breath". I have run up the computer with the case off to see what the air movement is like. lets say it is better but nowwhere like a breeze! Any tips for sites which sell fans will be greatly recieved!Next - About the power source suggestion. Yep you guessed it. i have 250 Watts. Site suggestions for a 300 watt unit once again greatly recieved!well thats about it guys. Ohhh RAM!!!!!! Thanks for that tip!!! I have 512 installed. I have a friend who is gonna lend me some spare sticks to see if that makes any difference!This problem doesn't happen within moments of operation. Sometimes it takes hours to appear other times it only takes minutes! So trial and error is the answer!Can you give me feedback on this little lot please guysCheersDaren :-beerchug

Darren,As well as all the helpful suggestions here, if it sometimes takes hours and other times only minutes I suspect it is not heat related.However just to make sure you can down load Motherboard monitor (MBM) and check the temp of CPU and case, that will give you a good indication of temps and you can log them over a period of time.http://mbm.livewiredev.com/HTH

Read Tomshardware.com....there is an article on power supplies yesterday, that included a chart showing what current components draw. using his numbers for current, and customizing the quantity column for my machine, I calculated my nominal power budget to be 288watts. Finally confirmation of what my friends told me about power needs for my amd xp system.Use this yourself, and read the article. one thing made clear, if your powersupply was provided as part of a low cost system, preassembled, it is probably of low quality. This means that voltage stability is possibly in question, that under load the voltage may not rise to meet the specified levels, and that degradation over time of the starting stability is real.He also points out that if your powersupply is cheap, you can burn it or explode capacitors at worst case, even before you reach high load levels.One suprise to me was the extreme power needs of additional harddrives. In my box, I added 2 additional harddrives. This adds about 60watts to my power budget.Highly worth learning about for adding stability to a pc.Bob Bernstein

Daren:If you are not overclocking your CPU or Video Card then I seriously doubt that your problem will be heat. If you have a heat related problem (usually intrinsic in us overclockers) you would get a system reset in most cases as opposed to a lockup. Secondly, case fans only cool the surface temps of the periphials such as the Mobo, vid card, etc. A case fan will not significantly decrease your core CPU temp and DDR memory doesn't get nearly as hot as RAMBUS memory so I don't think that is your issue. Even if it were, a casefan would NOT cure your CPU overheating problems. You would need a larger heatsink (preferably pure copper) and a larger (or higher RPM fan). For extreme overclockers such as myself, water cooling is the only real alternative to keeping the system stable. Again, I don't see this as your problem. The next question is why would adding more memory cause a drain on your power supply or overheating? Nope, I don't see a problem there.If you are getting lockups, it is generally a memory parity error associated with either a bad stick of memory or incorrect FSB setting. Again, assuming you are not overclocked, I am betting that your culprit is your memory.Mike T.

>If you are not overclocking your CPU or Video Card then I >seriously doubt that your problem will be heat. If you have >a heat related problem (usually intrinsic in us >overclockers) you would get a system reset in most cases as >opposed to a lockup. Not true. In some cases, a CPU fan may not be powerful enough for a CPU, in which case it would overheat. As well, if the contact between the heatsink and the CPU is not tight enough, cooling power can be greatly reduced. Double check and make sure your CPU fan is sufficiently powered for your CPU, and make sure that it is snug. If you have used some kind of cooling compound, try reapplying.>Secondly, case fans only cool the surface temps of the >periphials such as the Mobo, vid card, etc. A case fan will >not significantly decrease your core CPU temp and DDR memory >doesn't get nearly as hot as RAMBUS memory so I don't think >that is your issue. Not exactly. Casefans, unlike heatsinks, do not directly attach to a specific component. Therefore, their purpose is not to provide cooling for any components, but rather provide air for other cooling devices. For example, if you have a fan on your power supply, CPU, and video card, the amount of air blowing around in that case is going to be quite high. To keep the air flowing through those coolers low, you will need to keep a supply of fresh air in the case. To do this, people usually have a case fan blowing air in or out. This will evacuate any warm air. Another good idea is to have another fan blowing cool air in. That way, you can create an air corridor across the system where cool air is taken in through the back, and hot air is expelled out the side.>Even if it were, a casefan would NOT cure your CPU >overheating problems. You would need a larger heatsink >(preferably pure copper) and a larger (or higher RPM fan). You'd be suprised how much case fans can cool down a system. I have seen people who had massive problems with crashing have their troubles solved by getting some air flowing. Keep in mind, no matter how many heatsinks or fans you have, if there's no fresh air in the cooler to blow around, they are not running at their peak capacity.>For extreme overclockers such as myself, water cooling is >the only real alternative to keeping the system stable. Don't forget the ubiquitious Liquid Nitrogen coolers, for those diehard overclockers>Again, assuming you are not overclocked, I am betting that >your culprit is your memory. I'm more prone to say that a memory problem would cause a complete crash of the system, not just a crash isolated to a single application (unless I read the original post wrong, and the whole system does crash). I'm not sure what type of motherboard you have, but in the Asus A7V series, in the bios you can have the board detect and fix any memory problems before they can crash the computer. However, the types of crashes this fixes are quite rare, only occuring every ~3 months, so I doubt that this would be your problem. However, if you do have an Asus mobo, let me know and I can find the bios setting you will need to change.In closing...1. If you have an onboard temperature probe, see what the temps are. If the CPU is running too hot, check your CPU cooler for proper power and a tight fit against the CPU.2. Add a case fan to increase the amount of airflow through the case. Ensure that if you are sucking air in, you have an outlet for the old air to go out of, or if you are blowing air out, ensure you have an outlet for new air to come in through. If you find that leaving the cover open solves your crashing problem adding a case fan would be the solution.

Right Guys, To respond to you all at once! This is what is happening at the minute! The system on crashes when i'm using FS2K2 however that is the only real graphic intense program i have at the minute! When it does lock up the whole system goes. Can't do anything other than to press reset and start again! I initally thought that it was a driver problem as due to the fact that lock ups happen quicker once i have changed the driver! I have been following the prcedure of uninstalling and reinstalling the card! With the default drivers in situ (V5.12) This has keep everything stable for a week or so! Memory!!! I have had several sticks in the computer. All the same results! I have 2 *256 sticks at present! I will run the system with 1 stick at a time and see how we go! Cooling!!! I have installed a case fan! You have all produced many questions about temp. How can i check out the temp of the cpu. i have looked at the mother board temp program that was suggested and to be honest i just got confused! Fans and heatsinks! Where do i look for better ones! How do i know what is best for my system? Cheers Guys Daren :-beerchug

Seeing as everyone had answered your technical questions but no one's addressed your retail ones....Try www.dabs.com for your power supply and fans. I've had nothing but great service from them, fantastic and intuitive site, good prices (not the very best but never expensive), very smooth order process and they're a big reliable company. They replaced my 60Gb hard drive I bought from them after I cooked it (by accident).I don't work for them :-)IanP.S. Technically they've covered everything:1) If it's overheating then getting a desk fan on the open case should solve the problem.2) If it's a power supply thing, try removing peripherals until it works.

Daren - One more thing to try in your spare time :-) . These types of system lockups with FS2002 can also be caused by the sound drivers misbehaving. Click on StartRun and then type dxdiag in the box. Click on the sound tab and move the acceleration slider all the way to the left to disable it. Easy to do, can't hurt anything, and might even help with the problem.Trip

The only thing you can do in this situation is to isolate whether the crash is caused by FS2002 or some system component. To do this, you will need to run something system intensive to find this out. Try downloading game demos from http://www.microsoft.com/games and running them for a while. I would suggest Midtown Madness or Motocross Madness as they are relativly graphics intensive.If the crashes do not occur with any other games, there must be something with FS2002 we can fix. If the crashes continue with other games, then we will need to analyze your system further.As for good CPU coolers, my favorite are ThermalTake http://www.thermaltake.com I use the Volcano 9 Smart-and-Silent for my AMD Athlon XP 2000+. It runs on a thermal probe so that it's not always running at full speed, but it speeds up when you are running something like games. My CPU temp rarely goes above 50 C.

Hi Daren,This has certainly been an interesting thread to read. Many people with many different ideas, all of them good. However, there is one very simple fix worth trying that has not been mentioned. In the MSFS2K2 root folder, locate a file named FS2002.cfg (pretty sure that's the correct ID, I'm not at my FS computer right now). Back-up this file and then delete it. Now restart your computer and launch MSFS. The file will be rebuilt with all default settings. You would be surprised how often these types of problems can be attributed to corruption of this one file. Try flying for a while with all default settings and see if the lockups disappear. If they do, then turn up your settings to your prefered levels. Of course, if the problem persists, then just replace the new cfg file with the old one.Good luck.

Here is good method how to determine does your system have overheating problem and check overall system stability.First install hardware monitoring utility. Probably you have one on CD that came with your motherboard or just download motherboard monitor utilityhttp://mbm.livewiredev.com/Second download prime95ftp://mersenne.org/gimps/p95v21.zipPrime95 will push your CPU to 100% load so if you have stability problem prime will return error or just crash your system. While running prime observe CPU temperatures on mb monitor. If you get temperatures over 50-55C you probaly have overheating problem. If everything is ok in first 30 min leave prime95 to run next 12 hours.Other good utility is CPU stability testhttp://www.pcworld.com/downloads/file_desc...fid,7146,00.aspRun this for another 12 hoursIf you pass both tests your system is stable considering CPU, memory, power supply and motherboard.Petar

Update!!!!!!!!!Hey guys... Thanks for your help!!!I have been through all of your suggestions and have come to the following conclusionsA bigger PSU is already order 400wattsIn case cooling fans ordered!I monitored the cpu temp and am running at a hot 68 cBetter heatsink / fan ordered! with thermal gelSound accelaration reduction to the left!f2002 cfg file reconstructed!Have i missed anything!If not thanks for your help!If i have then please let me know!CheersDaren :-smile12
