overheating problem

Kind readers,

I have a problem with my Acer travelmate 7730g which I bought over a year ago.

The machine worked perfectly for over a year for the video work I do as a VJ. I run resolume on it (legal version no crack stuff on my laptop).

Since a couple of months my laptop shuts down whenever I work on video material or use resolume on it.

The 32-bit VISTA laptop has Intel Core 2 DUO CPU @ 2.10 GHz
4 GB RAM and NVidia GEFORCE 9600 GT

After hours of research and installing stuff like RMClock I have discovered it has to do with overheating when (and only) working on video (temp up to 90 C). The vid card heats up and shuts down the laptop.

First I thought it might be a software conflict since it worked fine for over a year. After re-installing windows with recovery disc it still happens.
I cleaned the fan, updated the vid card driver, did extensive virus checks, after re-installing windows I haven't installed any other programs but Resolume, the laptop is squeeky clean.

What is going on? Why is this suddenly happening after a year? And how can I fix this? Supposedly this machine is made for HD and I haven't even started working on HD material.

I really hope someone can help me.

Kind regards Sinan

 

So, did you physically pull the plastic covering your fan off, or did you just blow compressed air through the vent?

 

Did you clean off the old thermal paste/pads. It's often best to do it once you gut your notebook.

 

Renew the thermal compound on the Video card!! This should solve the problem. Also make sure you clean the FAN the hard way, not just blowing air into it.

 

Kind readers,

I took off the plastic covering and cleaned the fan the hard way. It wasn't even that dusty.

I read somewhere on the internet about the thermal paste cleansing but did not quite understand it yet.
I will look into this and also into the thermal compound. Thank you all for showing me the right direction. I will let you know if it works.

Kind Regards Sinan

 

Try this guide: How to apply thermal grease on laptop processor >> Inside my laptop

It may not be the same laptop you have, but the process is the same. *If the chipset has a thermal pad on it, leave it on.*

 

Depends on the heatsink, I was able to remove the thermal pad and apply Arctic Silver Ceramique on my Vostro 1500.

 

Try to get NVidia tuner (ntune) and see if the clocks are set to factory default, they might've got changed at some point. It'd look like this.

Go to Performance ---> Device Settings and set them back to factory default.

 

But for most people the safest option is to leave the thermal pad be.

 

You guys,

I opened the back of the laptop, screwed out the NVidia card and yes, there it was. The thermal paste was ripped. With a surgery knife I carefully peeled off the remaining paste. Luckily my dad had a tube of really good thermal paste from his job at home. We applied it, screwed back the NVida card and it worked like a charm!
It took us about 5 minutes to do this and my laptop works perfectly never warming up over 55 degrees! I can start editing again!

Thanx all for the replies! I am a happy man who just saved € 300.- by not bringin it to the repair station!
