HELP ! Macbook pro 15" misbehaving

by kptsher / December 3, 2013 2:41 PM PST

I have been experiencing a peculiar problem with my mac book Pro 15". the details of which are as follows:-
Mac OS X version 10.6.3
Processor 2.66GHz Intel Core i7
Memory 4GB 1067MHz DDR3
Intel HD Graphics -in built
NVIDIA Ge Force GT 330M PCLe

When using apps like i Movies, CS3 and while accessing my Hotmail account, the Mac just switches off, i.e. screen goes blank (black), keyboard lights come on and the fan is running. By holding down the power button the Mac can be switched off and restarted again.
Otherwise the Mac runs fine with no issues even while running apps like office, and watching movies or listening to music on itunes. I have tried replacing the Memory and Hard Disk but the problem is still there.
Would be really great full for some help on this.

I'm cringing a little

Something rings a bell about that GPU. But ask the person who works on your laptop to use the canned air and possibly replace the heatsink compound on all heat sinks.

Nvidia Issue?
by tombutler / December 7, 2013 11:06 AM PST

If memory serves, NVIDIA had a known issue several years back where the solder on their GPUs would actually separate from the motherboard. The normal use of the computer which allows the GPU to heat and cool down, is what did the solder in. Apple covered most of their devices with this issue. One of the companies that didn't was HP. My laptop died 24 days out of warranty.

Sounds like it is a heat issue with that GPU.
