Acer 6920 problems

First of all please escuse my faults, i'm French.
If I post my questions in this one is because I don't find the answer in my language.

I was under Windows Seven when i got some virus problems. i format my whole HDD and start to have some problems. sometimes the computer randomly stops. Often when i'm copying files or defrag the disk.
there, my laptop seems very hot. it shutdown when I play (whatever the game played the temperature are (according to SpeedFan) about 100°C))
I firstly think about dust. so i have clean by removing the trap at the bottom and cleaning the ventilation holes.
That change nothing. my computers stops 10 minutes after the game's started.
but it boot right now after it stops, (i've head that in case of a too ward hardware the computer will not boot right now after it stops)
metimes after a program ask a reboot and i say yes , the fan don't work at all after the reboot.
Please can you find a solution to me ? I don't know what i can do.

(I don't know if i'm using the right technical terms, please accept my apologies.)

 

Go to http://www.techpowerup.com/downloads/ and download GPU-Z.
Start it. Go to sensors and select log to file. Save the file on your desktop. Wait a minute then start a video game and play it until your computer stops. Once you manage to start your computer again, find the file on your desktop (it's default name is GPU-Z Sensor Log.txt) and post it's contents here. This way we'll be able to see the temperatures when your computer is idle and when it is under load.


Did you have any problems before the re-installation of windows?

 

Welcome to the forums, Ezech.
Sorry to hear about your overheating 6920G.
Is it possible that the fan's cable has come loose? Open up the bottom again to check.
Could also be a failing hard drive (given its tendency to freeze during copying or defragging).

I'd get in touch with Acer Euro Support if things get worse.

That was the GPU-Z log.

I have no problems before.
I was under vista, then under Seven. because of a network attack, I prefer reinstall seven in case of infection, I also upgrade the Bios to 1.14. but then the problems comes and never go.

I never touch about hardware, can you help me about the fan's cable ? where i can find it ? i'll check and/or give you any photos if you think that it can help.


Thanks for yours quick reply.


PS: @Tehsuigi as i could see you got an Aspire 6920G too. you run under Seven x64.A 64 bit version of Win Seven could run on my 6920G too ?

PPS: on this thread ( http://forum.notebookreview.com/showthread.php?t=468989 ) people talk about v1.16 bios. where could i find it ? i don't see it on acer website.

 

Well, this is interesting. Here's what I see:
1. Your starting temperatures are a bit high, but I wouldn't panic because of them.
2. At 2010-04-09 04:49:59 your GPU was under highest load. It appears that after that the load reduced. To me it looks as if it's a response to high temperature. A the end, the graphics card even lowered its clock to a non-gaming level.


I don't think that fan's cable is disconnected mainly because 15 minutes of gaming look a bit too long for a laptop to survive without a working fan.

You sad that you cleaned the ventilation holes. Did you open your laptop at that time? If you didn't, next thing you should do would be to obtain some compressed air and a painting brush. Remove the fan and clean it and the heat-sinks it's connected to. I'll let TehSuigi provide you with instructions on how to do that because I don't have a 6920.

 

First off Ezech, please find some way to cut down the length of your post! Maybe post the GPU-Z log as a text file attachment to your post.

Second, yes the 6920G can run Windows 7 64-bit. Just keep in mind that if you're starting on 32-bit, you'll need to perform a clean install to make the switch.

AndrejaKo, you're right. Doesn't sound like a fan problem.

Back to you Ezech, here's what I'd like you to do.
1. Turn off the laptop, unplug it, and remove the battery.
2. Flip the laptop over, and remove the six screws holding the large panel down.
3. With the screws out, remove that large panel.
4. Blow some compressed air (or just your lungs) to clear the mesh screen at the top of the panel you removed; if dust accumulates there, it'll choke your fan and prevent it from being able to blow enough air on the copper heatpipe.
5. Now, hold the fan blades down with your hand and blow the compressed air into the fan. If you let the fan blades spin, it might damage the fan itself.
6. Replace the large panel, put the screws back in, and hopefully things have improved.

I've left out removing the fan to clean the copper heatpipe directly. It's a little more complex.

 

Many thanks to you.

I've ever remove the back of my laptop, but this time with a dry air bomb i've clean the fan.and i have also use the bomb in the kind of grid in the back, near the power button, and a lot of dust come out by the fan blades that i was holding by my fingers.

in a normal use of my laptop i was 70°C, now i'm below 50°C ! just amazing.

I'll lauch a game soon, i'm nearly sure that's will be good.

Many many many thanks to you and your help ,and to have share your knowledge to me.

EDIT:

Waow. the max temp which was 100°C on my previous log is now 60°C. just 4 minutes after it get 50°C.

again: many thanks, or like we said , "Merci Beaucoup"

 

Awesome! Glad to hear our advice was enough to reduce your temperatures.
I recommend cleaning the dust from your system on a regular basis, or whenever you notice your temperatures starting to creep up again.

 

That's great!
