Aspire V3-771g sudden shut down (suspecting integrated graphic card problem)

stevenkom

I bought this laptop half year ago, and had no problem with it until when recently it started to suddently shut down, without any warning, like a sudden power cut.

Before I sent it to service, I tried to solve it myself, and apparently it has to do with graphic cards (initially I was suspecting the GT650M), because if the GT650M is enabled and running, the laptop will randomly shut down (between 5-15min), and if I disable it, and running only with Intel HD 4000, the laptop can stay opened for hours while running games.

But not much later, my idea was overthrowned, the laptop starts to shut down again, and still randomly, while there is only the intel HD 4000 working.

So I sent it to service, and when I went to take it back, on the service paper is says "indicated problem is solved by replacing the hard disk".

And I thought it is done, but no. After I installed Windows, after 3 hours it shuted down again.

I changed the windows OS (still windows 7 but another version), and on the reboot after installing Intel HD 4000 driver, the laptop shuts down again right after the welcome screen. I uninstalled Intel Graphic card driver, then it didn't shut down on start up, but it shut down while i was writting this threat.

I'm trying my luck here if anyone knows what problem my laptop has.

 

During the use of this laptop until its first sudden shut down, its temperature never reached above 76 'C, it never felt on ground.

 

And before each shut down, it works as fast, as good as before (no broken renderings during games).

 

P.S.: Useless service, they solved absolutely nothing.

 

Laptop Spec:

CPU: I5-3210M

MB: Aspire V3-771g

RAM: 4GB+2GB DDR3 1333

GPUs: Intel HD 4000 + GT650M

Another P.S.: I now can clearly feel the heat from SouthBridge on touch pad, before it's just a little bit of heat, that i can barely feel.
