North bridge cooling on laptop


My laptop is an acer 5742z.
Lately, it has been shutting down randomly.

I monitored the temperature and realized that the GMCH is overheating. The laptop has an integrated GPU, so GMCH overheat is the equivalent of a GPU overheat, on a integrated machine. It is in the north bridge.

I was thinking, couldn't this be fixed by applying new thermal compound on the north bridge? or somehow better attache the north bridge to the heatsink?

However, I asked a couple of local stores, they don't seem to think new thermal compound would work. Because they think the north bridge could be damaged. One store told me they could do a BGA rework, but that would cost almost 200$, so I might as well get a new one.

So, is this laptop beyond repair? should I scrap the parts and get a new machine?

By the way, the computer runs fine normally, it only shuts down if I use something graphically intensive, like a game. If I just surf the web (I am asking this question on said computer), it would have no problem at all, no matter how long.

thanks for your time.
