Question about Graphics Cards

1 Answer

Very loud fan!! Sounds like jet engine and make the computer shutoff.

I have had my pavilian ZV5000 for about 3 years and the fan runs constantly, never shuts off and most times is louder than the TV. The fan goes nuts even when the computer is just powered on and I am not doing anything with it. I called HP and they want $250 just to look at it. Anyone else run into this? Thanks This lap top has been away for repairs, three times during 12 mths warranty various faults and now it has been returned with the cooling fan running constantly at 50% speed and is very noisy , Problem is not due to dust build up, I think the lap top was over heating and has been set up to prevent this by setting a parameter to obtain fan to run full time at 50% speed . HAVE ANY OTHERS EXPERINCED THIS AT ALL,

In side you're ZV5000 are two fans. These fans sit on a spindle which spins. The spindle may be worn which is giving you that loud noise. (Or a fan blade could be bent or warped from heat).
The fan it’s self may be loose & can be tightened.
The only way to check if the spindle is worn would be to dissemble the ZV5000. With the correct instruction you can check the fans. (And also clean the fans & copper heat sinks).
Here is a link to do this you're self, including pictures.

It's worth taking a look & saving you're self a few bucks.

Good Luck & take you time!

Overheating of graphics card while playing games


  • Clogged fan

The main device responsible for maintaining a constant temperature of your video card is the fan present in the processor. If this isn't functioning efficiently it's quite obvious that it would result in your video card overheating. If you don't regularly clean your computer, it could be highly likely that your fan is clogged with dust.

This is one of the simplest causes of your video card overheating which can be fixed by simply cleaning your fan, preferably using a blower.

  • Broken fan

A follow up of the previous point, in some cases your fan maybe malfunctioning or stopped working altogether. This could simply be diagnosed by switching on your computer with its cover open and checking if the fan is functioning. If it doesn't happen to be working, you have your answer.

  • Overclocking

Pushing your CPU to its limits by overclocking can cause your video card to overheat. This can seem fairly obvious too as if you find your video card overheating and if you've recently overclocked your CPU, it would explain it.

  • Faulty Drivers

This is a rare cause, but depending on your video card's brand a badly developed driver could also cause your video card to overheat. If you use an unusual video card with questionable reputation this could be the issue.

  • Inefficient Airflow

While your fan maybe perfectly in tact and working, the location of your fan also matters. If there isn't sufficient air flow to your video card it can also cause it to overheat.

Those are typically the 5 main reasons to your video card overheating. If you have any other points in your mind, feel free to share them below.

Hello.. can anybody help me with my problem, i have a inno3d gt240 ddr2 video card, the video card seems to be fine when the computer is newly turned on, but after about 30 mins. of using the computer, the...


My suggestion is when was the last time you took the side cover off your computer to check the fan on your video card. It sounds like the card is heating up and causing the computer to shut down. You can try blowing out the fan with air to make sure it doesnt have some larges peices of dust/dirt or that the fan isnt worn out. If the computer keeps running with the side cover off that would confirm an over heating problem with the computer. While you have the side cover off blow out the whole machine especially the power supply. Computers are dust magnets. While your using the computer if you have a video game that is graphics intensive run it and keep your eye on the fan of your video card to see if it stops turning at any point.I would also look really hard at the fan or fans on your computers processor to see if it is spinning freely. When your blowing out your computer with air blow air on the fans of your processor to make sure it has no dirt in it and it is spinning freely. If after 30 minutes your computer continues to run with the side cover off then either its time for a new video card or a new fan on your processor. Because one or the other is worn out.

I hope this helps you out.

The fan on the ati radeon hd 2400xt video card runs constantly, any ideas of how I can get it to stop


you don't wanna stop that fan. the chip in your video and is very similar to your processor on your motherboard. it runs very hot, hot enough to even melt your card. if it's running constantly maybe your computer is in a very warm spot or your working the video card too hard. either way let the fan run or you'll severely damage your ard.

I installed my brand new ati radeon 5870 into my dell precision t3500 and when i start up the computer a long beep sound with a loud fan and the monitor shows nothing


You've left something unplugged!Check the motherboard connections and the power connections for the card.Speaking of power,check the system requirements for that card.Do you have enough Watts to run it?Let me know how it goes ,if it won't work with the card installed.Put the computer back the way it was and see if it runs.It will help you to remember what you unplugged to install the new card.

Card started making loud clicking noise i have tried blowing dust out of it when i start my computer within a few minutes clicking starts again


Hi, couple main reasons to get loud clicking in a computer. First is the hard drive, so if you can turn the system off and disconnect the power and the information cable from the hard drive, yes your computer will not boot all the way back into windows but that is ok since you just want it running for awhile to see if the clicking stops. Next thing would definitely be the fans, any fan in the system, the blade part of the fans can get loose sometimes and start to hit the sides as it spins around, you need to be sure about which part it is that is causing it, it can come from the power supply fan, the case fan, the video card fan, the cpu fan, and you might have more than one case fan, test by disconnecting one at a time just make sure to disconnect the device too so you do not over heat anything. Once you identify which fan just replace it, if its something like power supply or video card, unfortunately you might want to look into either warrantying the part or buying a new one.

Loud noises


it is very possible that that fan is mulfunctionning overheating the videocard. replace the fan. (you can by the fan seperate from radioshack or some local computer store. (sometimes it is cheaper to replace the video card since it comes with it's own fan.) but of course it depends on what card you have.
