vgn-z11wn over heating problems with windows 7 64bit

Hello everyone!
At first, i want to apologize for my really bad english.
6 months ago, I have updated my vaio z11 model wn-b to windows seven 64bit, following the guide that i found on this forum. At first everything was working and i didn't have any problem in speed mode too.
Now when i put the vaio in speed mode and i play a game in low quality the laptop beacomes really hot and after a few minutes it shuts down. It didn't ever do like this on windows xp. Has anyone a problem like mine?
I want to send my laptop to vaio support, but i don't think they would accept it because they don't provide any driver for my specific model(but they provide them for the z21 which is almost equal!).
What do you think i should do??

 

So, does anybody have my same problem?
I just called vaio assistance and they said me that they don't support windows 7 installation on my notebook, so if i want to send it to the assistence on warranty i have to put back vista or XP. Can someone please help me?

 

I get this sometimes too - although it started quite a bit before I put Win7/64 on it. I suspect it might be the graphics card/drivers as I can really hammer the CPU and all is fine, but if I start a 3D game up then it'll eventually bomb out if the weather is hot.

I was using the tweaked drivers from the forums here, so maybe the original drivers didn't push the card as hard as the new ones?

Have fun

Are u sure the fan was on, when the computer died? Mine had similar problem, that the fan sometimes didn't kick on while doing something CPU demanding (like watching a flash video) while being in the Silent mode.

I was trying to repair it by myself, but probably screwed up and broke the motherboard.

I sent it to the repair centre and they exchanged MB for free! As overheating is their problem. That fan problem happened once again though. From that time I don't use Silent mode at all and that problem didn't happen - knock knock. So try to use Balanced mode (Performance mode while gaming), and if it'll be still overhating, send it to repair center. It's not problem of Win7.

 

@Finn I have higher temperatures just when i switch in speed mode, also keeping it in idle. If i try to play a game or a fullHD video it gets hotter and it shuts down every time. Currently I've installe the latest official drivers for win7 64 bit.
@Metsn Unfortunately mine is not a fan problem, fan is always on and a little noisy in stamina mode too! I can't send it to the repair center right now until i'll put vista on it because Sony doesn't support windows 7 on first generation z(that's incredible because it has the same hardware as the second gen!).
I'm starting thinking about putting vista or xp on it and try if it is still hot or it gets warmer.

 

My Z is also first generation and it was not problem for repair center, as such overheating is not a problem connected to software, but to hardware. Various drivers can cause various temperatures, but except some complete error I didn't try any drivers which would make my GPU go over 100C.

Anyway...if you're worried, why don't you do complete backup of your HDD, install Vista and send it to repair center for overheating?

Before that try different GPU drivers though.
