VGA Problem in DELL - Absolutely fix or not?

Dear all,
5 month before, i bought a 2nd dell D630 from some people. After 2 month, my laptop having Problem with the VGA ( NVIDIA 135 M) . I lived in Viet nam, so there are no agency (or authorized dealer ) in Viet nam can help me to fix this problem. I already talk with Dell Support and they suggestion that send it to the Malaysia or Australia to fix VGA problem. But i can not.
After that, i go to the shop in Ha noi, and fix this problem(fixing only - not replace main board). But after 2 months, VGA problem occur again.
Now, i decide to replace the main board. But i am a little worried about : Did they absolutely fix NVIDIA problem in the new main or not?
Did you know about this problem? Please help me because the price of the new main board are very expensive for me.
Thanks.

 

What is your problem with the VGA, what happens?

 

The problem are NVIADIA, it is already announced by DELL.The fist GPU too hot, (GPU temp about 70 oC - by Everest soft) and after that, the screen are shrinks with the vertical line, and appear Blue screen with nv4_display eror

 

Ah ok you mean the GPU...well the issue won't really be "fixed" at all i think. Dell does give an extended warranty for models with the GPU's having this problem but that's about it.

btw....70c isn't too hot for a GPU...check with nvidia system tools to be sure if you're getting the right temps. What did they do in Hanoi to fix your laptop then? If the GPU dies it needs to be replaced, there is no fixing it.
