My G73 has been shutting down lately when I attempt to play games. Specifically it's been happening after about 15 minutes of playing Mafia II (which seems weird to me b/c I wouldn't even call that a super graphically-intense game, at least not compared to some...)
Read some other threads and stuff on the various interwebs about this issue and I think I've pretty well concluded that it is likely due to old thermal compound, fans clogged with dust, etc. I'm pretty sure my BIOS and AMD drivers are up to date so I don't see why that would be causing the problem as some threads have suggested (what does that do anyway, cause the fans to spin faster? Or increase the shutdown threshold?) Weird thing is sometimes I have to reseat by battery after this happens... but not always. I have monitored the temps and they definitely get waaay up there when gaming.
So I'm thinking of performing the equivalent of open heart surgery by taking the thing apart to access the GPU. I've built PCs before and used the thermal paste so I'm familiar with those concepts, but I've never taken apart a laptop. Definitely a little apprehensive. There is a pretty good video on YouTube though of a guy going through the whole process.
Some questions/concerns:
1. Which compound to use?
My inclination was Artic Silver b/c I know that's good stuff and have used it on CPUs. But is it ok for GPUs? Is there any difference? After all I guess a GPU is really just a CPU mounted on a graphics card, right? Or is there some special GPU paste I need to look for? Also I could have sworn I've read something about Artic Silver shorting things out? So that worries me a little...
2. As long as I'm down there shouldn't I replace the paste on the CPU as well?
3. Will all this effort/risk really even be worth it? I've read some stuff where people are saying it dropped their temps like 20 degrees and others who are saying it only helped about 5 degrees worth... would suck if I did all that and it still overheats! Maybe an alternative to this is just doing a thorough fan blow out with the hair dryer on cool as some have described...
4. What are other ways for me to cool this rig down? Can you upgrade the fans or anything like that? This product looks kind of interesting...

thanks
