Re: problem!

Never screw or un screw or even try to open up computer and work while the power is ON.
If everything is working fine on your system then I suggest not to worry. But if your video is completly gone we need to diagnose the video card (as I assume you have installed the fan and heat sink over video card??)
Hope that helped!

There is problem on my graphic card. It is over heating because of it's fan. I buy a new termal paste and oiled the fan but it is still over heats and shuts down itself. sometimes it flows air v

If the fan is operating and the heatsink is in contact with the chip and it is still overheating then there is a bigger problem than just cooling. You could try a PCI slot fan and mount it next to your graphics card. But I can't see this making enough of a difference to a graphics card as old as yours. If you aren't playing games then just try removing the graphics card and using the onboard graphics port.

How to avoid replacing the motherboard due to a video issue

This tip applies to the Dell Inspiron 5160 but may apply to other models, even makes. Note: This requires a moderate skill level to do.
The video works fine intermittently pixelates or goes blank even using an external monitor.
Spend $200 on a motherboard or check this. Take the keyboard out & remove the lcd screen assembly.This will rule out the lcd & inverter as a problem. The lcd assembly is fairly easy to remove as a complete unit, no need to take the whole thing apart. Then hook up an external keyboard, mouse & monitor. Power the unit up. As soon as there's a picture on the monitor you can now try this test to verify what I've come across. Lightly press on on the metal shield directly on the screw that holds it to the video card assebly. This is a little left of center under where the keyboard was & it is the only screw that is remaining holding the shield in place. If the screen starts to act up, then you have to do this to correct it.
Power the unit down, disconnect the ac adapter, remove the battery & disconnect all the externals you connected previously. Now put the unit on a solid surface with ample light to work in. Remove the metal shield you pressed on by removing the recessed screw holding it down. Slide the shield toward the rear slightly, gently lift the right side of it & slide toward the right side of the unit to remove it. Remove the 2 screws in the center under where the lcd was. Turn the unit over & remove all the screws from the bottom, including the hard drive itself. Note the screw under where the hard drive was & under where the battery was, be sure to remove them also. Flip the unit back over & take the top plastic off, theres a plug for the mouse pad that needs to be disconnected, it just unplugs, no ribbon cables to fuss with. Now this exposes the cpu heat sink & fan. Remove the heatsink & fan assembly. Remove the video card, 2 screws diagnonaly hold it down. Theres a small heatsink by the cpu covering some transitors, remove the 2 screws holding it down, unless it just pops off with the bosses still attached like the one I was working on did. If this happens, then you found what caused the whole problem to begin with!
Here's the fix:
You'll need to separate those screws from the bosses. Just hold the boss still with a needle nose plier while removing them. Ok,here we go. Using a small flat head screw driver,such as a jeweler's, carefully scrape the area where the bosses would be attached to the board,taking care not to scratch the motherboard itself. It doesn't have to be super shiny,just as good as you can get it without getting crazy. Clean the bottom of the bosses using the same method. Now you need epoxy, I reccomend a one to five minute epoxy like Perma Poxy Clear from Permatex. To do this whole repair I removed the entire motherboard, but it's not neccesary,just makes it easier to work on. Mix a small amount of epoxy & dip each boss bottom first (the side with the nub that goes in the board,not the sides or the threaded end). Do one boss at a time. You got to be quick, since the epoxy will set in 60 seconds to 3 minutes,depending on which epoxy you chose. Install a boss onto the board,they are 2 different sizes, so you can't mix them up & hold it firmly in place for about 20 seconds, then do the other,same way. Once both are in, you should still have a little time before the epoxy sets, so press & hold them down firmly for atleast 60 seconds. Ok, the hard parts are over! I'd wait 2 hours before starting re-assembly. Reverse the process to reassemble. When you tighten the screws for the bosses you fixed,take care to just snug them. There's not much holding them solid to the board, although it's surely stronger than factory now. When you put the video card heat sink in tighten those real tight all but the one closest to the cpu, this one is one that was repaired. that one just gets snugged.Re-install the cpu heatsink & fan assembly, make sure to wipe all the old thermal paste off & put new on the cpu, use Artic Silver or equivalent. I usually put a dot (this is about the size of a pencil eraser) dead center of the cpu & 4 additonal smaller dots near each corner. You don't want it oozing out the sides. When you tighten the video card itself back down, you should really crank down abit on the 2 diagnonal ones you removed earlier, don't go nuts though. When you get to the top metal sheild part, the same applies to the recessed screw, tighten it hard. Re-assemble to the point where we were in the beginning for the test, leaving the keyboard & lcd off. Put the battery back in, plug all the externals back in the way it was for the initial test. Power the unit on & perform the same test as in the beginning. The screen should work well, you'll find if you press too hard the screen may act up. This is as good as it gets,hopefully it takes significantly greater force if it does happen. The reason this screen problem was those loose bosses allowing the video card to move ever so slightly & over time has either loosened the connection in the socket or the connection at the motherboard itself. There's no absolute fix other then to replace the motherboard for a current cost of $200, not worth it for an older machine. If you're a pefectionist, like myself, you can try to stablize the video card further by finding a way to hold it from moving/vibrating by fashioning a bracket or something on the end that that the card plugs into. I'm still working on that part at the moment, I just wanted to post this while it was fresh in my mind. I've included some pics of the board & bosses so you can see what to look for. It's very obvious. I hope this helps, I could not give a complete guide to this repair in laymens terms, nor go absolutely screw by screw on this repair due to it would take about 4,000,000 words & whole lot of pics to do so. Like I said in the beginning, this repair is assuming that the person attempting this has a moderate skill level with taking things apart or knows what they are doing. A complete beginner should NOT attempt this repair!
Good luck, not a total gauruntee for a fix, but it worked for me. The extra re-inforcement of the video card is up to your own creative talent, just make sure whatever it is doesn't interfere with the keyboard installation or pushes that metal shield up.

Need replacement FAN for ATI Radeon HD2600Pro graphics card. Where are best sources?

Some ideas,




Skipped past the ATI Radein HD2600 Pro, (More of an Nvidia fan), so I don't know how they have the fan/heatsink attached.
Don't know if they used Thermal Glue, or Thermal Paste for the heatsink. (Or a thermal pad)

It is Always best to replace the thermal compound. Cheap insurance.

A) Thermal Pad:
Remove the heatsink.
Carefully remove the pad the best you can, then use Q-tips dipped in Isopropyl Alcohol to soften the remnants. Follow with a plastic scraper, (Old credit card?), and more Q-tips dipped in alcohol.

Make SURE the top of the GPU is CLEAN. Then properly apply fresh thermal paste to the top of the GPU, and set the fan/heatsink assembly in place. Lock the fan/heatsink assembly down.

Graphics Processing Unit,

The GPU used in an ATI Radeon HD2600 Pro graphics card, is an ATI RV630,

B) Thermal Glue:
Requires using a hairdryer set to low heat, and constantly moving the hairdryer's nozzle around slowly.
Once the glue softens gently twist the heatsink loose.
(Wear gloves)

C) Thermal Paste:
Remove the heatsink.
Use a clean plastic scraper, and plenty of Q-tips dipped in alcohol on the GPU.

(Isopropyl Alcohol. Commonly referred to as Rubbing Alcohol.
91 percent is best, 70 percent will do in a pinch. Advise against 50 percent.
50 percent alcohol, 50 percent water.

Isopropyl Alcohol is EXTREMELY FLAMAMABLE.
Use in a Well ventilated area with NO sparks or flames present.

Once you set the heatsink, or fan/heatsink assembly in place, and have it secured, look at a side view of the graphics card.
Room well lit, and a light background.

See if the heatsink is sitting flat. You do not want it sitting at a slight tilt.

As you can see, I am trying to steer you towards making sure the thermal compound, is in good shape. It is best to just replace it. Thermal paste is cheap stuff.

For additional questions post in a Comment.


{To Add:

Basic construction is a plate of metal with tall, thin fins protruding from it.
The plate of metal absorbs heat from whatever object it is placed against, (In this case a GPU)
The tall, thin fins absorb heat from the plate.

The fins then radiate the heat away.
With a fan used in conjunction with a Heatsink, the air flow from the fan helps carry heat away.

Thermal Compound:
{Thermal Paste, Thermal Glue}

The top of a Processor, and the top of a GPU are not perfectly smooth.
A magnified view would detail, 'Hills, Valleys, and Pitholes'

Same with the bottom of a Heatsink. (The plate)
When the Heatsink is set on top of the Processor, or GPU, there are air pockets created from the imperfections of the two surfaces.
Air is trapped in-between the two surfaces.

{Heatsink on top of Processor, or Heatsink on top of GPU}

Air is an Insulator. Not a Conductor.

Thermal paste fills the voids, (Imperfections), and is an Excellent conductor of heat.
Thermal paste, (or a Thermal Pad), can dry up over time.
The thermal conductive properties are gone, or negligible ]

Very noisy cooling fan, model A4010H 12C, d.c.12V o.14A. Would be grateful for advice where to obtain a replacement. Thanks Ted

you could try Ebay you can purchase computer fans very cheap but of good quality bonus is they will be delivered to your house if you have a registered account or you could go to a computer shop to get one
hope this helps

One more time,

Some information on installing a GPU cooler.

(Also check out the other videos to the right)

[ GPU stands for Graphics Processing Unit. The ATI Radeon X600 series uses an ATI Radeon R300 GPU, ]

If you are replacing using more than just a Fan, such as using a GPU cooler that also has a Heatsink attached, do not forget to Thoroughly clean the top of the GPU's case, and Properly apply fresh, new Thermal Paste.

If you have Any questions regarding installing an aftermarket fan, or GPU cooler, please post in a Comment.

Fan seems to vibrate periodically then return to quiet for some time. Does it require replacement? Unit is 12 months old. John Meersman

no,if is vibrating does it mean that is something wrong maybe is not fixed proper or the load of program is too much for it,check if is proper fix first.

Does the video card have a cooling fan on it or a passive heatsink? If it has a fan then make sure it is working when the computer is on. If it does not have a fan you could try installing a small fan on the heatsink to help cool it. Is your powersupply rated high enough to work on that video card? High end video cards are very power hungry and might be taxing your current power supply. If the voltage drops it could cause the video card display to shut off...especially when playing video games at high res. Verify that the video card is properly seated into the slot and you may also want to try and remove the card, clean the contacts, and the re-insert the card. And if you are using software to overclock the card or if you computer multiplier/FSB has been raised then this can raise the clock speed of the agp/pci-express port and cause video problems. Also verify that the agp/pci-express voltage is adjusted to what the video card requires.

RX9550SE-TD128 graphic problem

First try turning down the setting on the games. If that doesn't work try getting a better cooler for your video card, one that isn't passive. Like a zalman heatsink and fan with, video ram heatsinks.

Try installing the drivers in Safe Mode.
This doesn't really sound like overheating if it runs fine otherwise.
You could also try removing and reinstalling this device from Control Panel/System.

Graphics breaking up

Well, just for kicks... It's a heatsink and not a fan on there? Maybe when playing games, open the case, put a household fan on to circulate the air especially on the videocard. Heatsinks are a temporary replacement in case the fan goes out on the video card. I use heatsinks as a quickfix for video cards at my job...but they aren't playing games on the PC, so the video cards aren't really going to heat up. Yeah, it does sound like a faulty card, but maybe the above tips will allow you to still play games with the card.
