From what your saying your correct, it does sound like the graphics chip. Its the solder that they use on certain models, its very poor.
It isn't a seperate graphics card on your model, it is actually a graphics chip that is soldered to the board. It can be replaced by certain laptop repairers. Saying this, once it has been replaced the same thing can just happen again a few months down the line. Maybe think about a new laptop at this stage?
Hope this helps.
