Acer 5750G overheating

Hi,

I have had my Acer 5750G for about a year now, but after having it for three months, it started getting very hot, especially when playing games.
So I bought a cooling fan to put under my laptop. That worked for one or two months, but then it started getting very hot again while playing games, even when playing small 2d games. Since then, I had to put a table fan on the highest power pointed directly at my laptop. Yesterday, it went too far. I was playing a game (this time without any fan, I was at school), and my laptop actually overheated and turned off.
Even when doing something simple like browsing the internet, when my computer is not getting extra cooling, it gets so hot, that I can't even put down my hand on the laptop.

I have checked the cooling fan on the laptop itself, but it's the GPU (which does not have a fan) that's getting so hot, along with the RAM sometimes.

Does anyone have a solution to this?

P.S. Acer Tech Support is no option for me, since here in the Netherlands, the Acer Tech Support apparently thinks a CD-ROM is the same as an optical disc drive. (seriously, the woman didn't have a single idea what she was talking about.

 

Clean the vents and it that doesn't help- apply high quality thermal compound on CPU and GPU.

Other than that there's not much you can do apart from making sure the radiator makes good contact with CPU and GPU.

 

I'll try that.
Thanks for helping
