Guessing as mentioned opening it up and cleaning etc is the only way. Did get out the dust when the gpu fan was replaced last year by a tech.
But the symptoms have come back, stuttering hd films and programs that stop responding etc before it freezes up sometimes.
Wow awesome ambient temperatures....therefore....
This really sounds like bios throttling to me. the stuttering mainly. check your cpu usage when it happens with ctraltdel, then select view and select kernel times. If your cpu is 100% and that little red line is close to or AT the top, then it's definately throttling. (unless your cpu is from the 60s)
I've heard alot about ppl using windows 7 with the new drivers 150+ and the cards running a lot hotter than usual. I suppose thats fine if you have a 9000+ series card that can turn off when not used, but ours dont have that ability, so getting rid of powermizer is uber suckage. You sure it's gone too? there might be some advanced settings you haven't turned on, google around about it.
Unfortunately it's throttling to save itself from exploding, the only way to fix is to find why it is. Now is the cpu always hot too or just the gpu? cause thats a whole different thing if BOTH are acting super hot. Can you feel the fans at all? have anyway to force them on full like with the i8k fan control?
This is all to find out what exactly is the issue, but really, I think it's just dust. But who knows! want to make absolute sure.
Mine overheats every 4 months from dust buildup, and I gradually lower my clocks throughout the year until I finally clean it.
It builds up really fast, mostly cause the air tends to blow through the inner (towards center of notebook) part of the heatsink the most, so thats where all the heat exchange is, thats where all the air goes, thats where all the dust goes, and once its blocked, things get really bad fast.
