Acer 7741g GPU Overheat 105+ degrees

Hello,

This is my first thread here. I tried to search for similar issues, but i could find none.
I own a laptop for about a year: ACER 7741G, I5, 4GB DDR3, ATI 6550M
I have an issue with the graphics card. When I play games like WoW, EVE Online, and even Diablo 3, all of them at low/medium detail settings, after a while the GPU starts overheating to over 105 degrees and the laptop shuts down. While overheating, the processor stays at about 70-80-90 degrees in full load. Also this overheat appears to be random.

I have no idea what is the trigger for this overheat. I cleaned the fan with compressed air, tried a lot of graphics drivers and ingame settings but without any success.

Also i could not find any similar problems on the internet as well.
So if anyone has any knowledge of this issue, any help/suggestion will be appreciated.

Thanks.

 

You should probably try re-pasting GPU with new thermal compound and while you're at it making sure that the heatsink is in contact with the GPU itself.
Unless off course it's still covered by warranty in which case you can simply send it to Acer support to fix it.

 

Just be careful with the re-paste. Many people tend to overdo it and actually make it worse. It only takes a thin evenly spread film and Artic Silver is the top of the line when it comes to paste.
It is strange it just started happening if you've had it for a year.
Is your fan working?
Did you just start playing graphics intense games lately?

 

Hi!

Actually I noticed the overheating couple of weeks after i bought it. But I thought it was related to some game. But I think the games aren't the issue. Since no one else complained about this problem, it has to be a hardware issue. The fan works. It worked all the time. I will strip the laptop and see if the GPU is somehow detached from the heatsink, just how Mr. downloads suggested.
I have been playing games ever since i got it.
The laptop is out of warranty and i have to do it myself.

Thanks for the replies, I will search for this paste.


Any other suggestions are welcomed.

 

Okay today bought cooling paste. Opened the laptop, came apart nicely, removed the heatsink, nothing suspicious. The stock cooling paste was still there. It was in good condition. Anyway, removed the stock one, cleaned the surface, reapplied my paste, screwed the heatsink back, put the laptop together. I turned it on, everything okay. Temperatures in idle all normal. After about 3 hours came back home and started Diablo 3. Played for about 10 minutes, and when I ALT+TAB to check temperature, there it was, again 100 degrees.
I put it on power saver just to finish the quest and boom. Shut down. The safety kicked in.

Okay, so now i know it's not the heatsink or the paste to blame.

Any other ideas?

Thanks.

 

Hello again!

As a last resort, I re-installed the OS and just a few basic programs and drivers. The video driver is the one from the bundle software. Now in every game I try the GPU temperature tops at 61-70 degrees MAX from 1, 2 hours of gaming. The CPU also stays at 70 degrees max in full load. I mention that now the graphic details are set to a higher value than before.
So whatever was the problem it seems it was software related. I am still monitoring the temperatures.

 

Not cool (sarcasm) that software can cause it. I have heard of it before, just never experienced it thankfully. I need to change my mindset/paradigm to consider software when it comes to overheating.
Glad you got it sorted out.

 

Hello again,

Okay so i was hasty. The issue is not gone. The overheat is still random.

Listening to any suggestions.
