    Applying thermal paste to video card

    Hey folks, I have an N81vp that I purchased a few years back. It's been overheating and I'd like to reapply some thermal paste. I've looked inside the machine and applying the thermal paste to the CPU seems very straightforward. My only concern is with the GPU. Upon pulling out the videocard I noticed that many components had thermal pads on them. When applying new thermal paste I want to remove all said pads and apply thermal paste to those areas, correct? Or am I just removing/reapplying thermal paste to the main component of the GPU?

    My GPU is at 100C under load so hopefully this solution will help.

    Thank you.

    It's a bit difficult to make out in that pictures; you should only need to repaste where the pad meets the GPU. The other areas you have marked "2", "3", and "4", don't appear to have paste (or am I wrong?).

    2 3 and 4 seem to have some sort of pad but they do not make contact with the copper bar. I'm assuming I just need to take off the old thermal pad marked 1 and apply new paste.

    thermal pads can be exchanged on other thermal pads. They are on memory chips.

    Use alcohol to clean main gpu's die (1) and heatsink.

    Thank you, but now it seems that noise is coming from inside my laptop (near the CPU?) when I use an internet browser, i.e. when I open new tabs, change between tabs, scroll through a webpage, etc

    Anyone know why this would be?

    This happens strictly when using a browser? What's the noise sound like? You may have not seated something correctly, and now it's rattling - or a fan is making the noise.

    It happens when I move around in a browser and when I move around any windows. I'll try to take all the components out and put them back

    Be extremely careful. Make sure you're grounded so you don't short anything when you do this, and try not to flex (bend) the board or any of the components.

    Thanks. The sound is very high-pitched when I play a game. Do you think it's my videocard making the sound somehow?

    High pitched? Hmm, I don't think I've ever heard a GPU make a noise like that. I'm not sure if what you're hearing is mechanical or otherwise. It might be a fan, but fans tend to make more of a "rattle" kind of noise when the bearing is going out, or when they're dirty.

    Let us know what you find out.

    The sound is hard to describe but it's definitely from the GPU. After uninstaling the drivers the sound went away. Sadly though, I cannot access Windows so I'm currenly running my machine off of a flash drive with Ubuntu. I cannot begin to think what I did wrong; I only uninstalled the ATI display drivers and as soon as I restarted I wasn't able to get to my desktop.

    Actually, would you happen to know how to able my onboard graphics? I couldn't find any option to do so in the BIOS. Regardless, I'm assuming I'm running off my onboard graphics at the moment since I'm able to use Ubuntu.

    I attempted to take out the GPU and boot up, assuming my laptop would defer to integrated graphics, but instead I didn't get any video.
