NO, the card is integrated. cant purchase graphic card alone.. it should be the whole motherboard.. since it is a laptop computer.. so there is no other solution with this>? I thought the card will be reset if I heated it and will be okey again.
What happens to a laptop gfx card is that when you overheated it only 2 things happen. You fry the chip or because the heat from it unseated the ball bearing solders on the board. You can take your laptop apart and put the entire motherboard (with all the heatsink remove) and bake in in a oven hoping the chip will reseat itself (but rarely do this even work only luck). Most often cases with laptop gfx cards is inadequate heatsinks and ventillation and fry the chip.
I know because I had HP Pavillion laptop with Nvidia and it died twice because of bad design and ventillation (courtesy of HP) and had to send it to retailer to get it replaced, unfortunately my warranty was over on the second death.
If you still have warranty better send it to get it fixed, if not, too bad buy a new laptop with adequate cooling. But still not that advisable on hardcore gaming with a laptop.
