My Graphics card is overheating and I don't know why....

from Demigod Forums

Hello everyone, about a month ago the fan on my geforce 9500 GT broke and it overheated and fried. I replaced it with a Geforce 7950 GT that had a much better fan on it. However, Today I was playing a mod for unreal tournament 3 called the haunting (really good mod if you have UT3 you should check it out), and I had been playing on and off for about 3 hours or so, when all of a sudden The screen announces it has no connection and goes to sleep, and the sound kept looping until I had to manually restart it. I unplugged everything, sat it on my bed with the side panel off for an hour or two until it felt sufficiently cool, and then plugged it back in and restarted the game. I started playing a round, and after about 1-2 minutes the same thing happened as before. I dont understand why it happened so fast that time. Anyone know what happened or how I can fix this? The fan on the 7950 is working perfectly fine so I dont know whats causing it htis time.

Had the same issue, my guess is that nvidia screwed up the fan speeds in one of the recent driver releases so the fans dont throttle up under load. My 2x280gtx's were only running at only 30 percent fan speed even at maximum substained load. Got rivatuner and set it right, try that - certainly cheaper than a new card!

Well it is a used card wizard. Its pretty clean however. But since I got it everytime I've turned on my computer Ive gotten a message saying that its not recieving the power it should be and I need to attach the power connector. It stopped saying that though  a few days before it started doing this.

 

@Rantoc that wasn't the problem in my case unfortunately. I could hear the fan kicking on when I started gaming.

That may be the cause of your problem.Underpowering electronics is always a bad thing and will lead to all sorts of trouble,including overheating.

If your card has an auxillary power connection,by all means hook it up to the psu.

Problem is I don't have it. I'll talk to my friend and see if he forgot to give it to me or something.

Maybe you have underpower PSU, like I did :). What is your PSU rating? If you are using those low end come with casing PSU then I suggest you change to a better one. You could estimate how many watts you really need by using the power calculator from here-> http://www.journeysystems.com/?power_supply_calculator

And you can also try things like this to help you cool your GC down-> http://www.xigmatek.com/product/air-battleaxevd964.php.

Just a suggestion :andrew:

I found one on Amazon for under 5 bucks.  LINK

If your friend no longer has it,you should be able to order one or pick one up locally for very little cost. Many newer psu's may have a connector for graphics cards already,as does my Enermax 600 watt unit. In that case,no adapter is needed.

But maybe it just your online game issue? :andrew:

Maybe you should just try reinstalling it. That works more often than not haha.

I tried that and it didn't work. When I updated my drivers, I also downloaded the ATI Catalyst Control even though I already had it. I think it may have screwed my system up a bit. This software seems really useful, because whenever I run games like Crysis my system crashes from overheating.

I also downloaded the ATI Catalyst Control
Unfortunately,the description of EVGA Precision states that it is for GeForce cards. You will need to look for something similar for your card.Perhaps ATI Tool will work for you. It claims to work on both ATI and nVidia cards but I haven't tried it.

What card are you running?

Edit.The ATI Tool appears to be way out of date,no Vista support.

For those with Radeon HD 4000 series cards:

According to bretware, a user needs to follow these simple steps:

1. In Catalyst Control Centre, make sure clock and memory settings are correct and turn on Overdrive
2. Create a Catalyst Control Centre profile called "fanspeed"
3. Navigate to C:\Users\UserName\AppData\Local\ATI\ACE\ and you'll find an XML file titled "fanspeed", open the file in Notepad or your preferred editor. The file should resemble the following:

<Feature name="FanSpeedAlgorithm_0">
<Property name="FanSpeedAlgorithm" value="Manual" />
</Feature>
<Feature name="FanSpeedRPMTarget_0">
<Property name="Want" value="0" />
</Feature>
<Feature name="FanSpeedPercentTarget_0">
<Property name="Want" value="65" />

4. As shown above, change the "FanSpeedAlgorithm" value to Manual and the "FanSpeedPercentTarget" value to 65 (or your preferred fan speed in percentage)
5. Save the file and reload the "fanspeed" profile in Catalyst Control Centre.

If you're unable to locate the XML file, you may be required to set your operating system to show hidden/system files.

Bretware adds that "you may have to select the profile everytime you start the computer, but it will work until there is a fix or better info so i can figure how to change the auto target temp".
