G50vt gpu heatsink supernova temperatures

Hi o mighty community of notebookreview forums.

newbie here, got this problem with the gpu overheating, thought maybe someone here would have the idea of whats happening.

After the crashes started I figured by the looks of crashes that it was the overheated gpu issue (random rectangles going black on the screen, one window contents sticking to another, etc). With nvidia drivers installed it crashed nearly every 10 seconds, sometimes recovering, sometimes not. After uninstalling drivers I'm able to work without crashes but dammit I bought this thing for gaming not for office programs. Took off the bottom panel to test temperature via "finger" method. So what I've got here is the gpu heatsink that is in the "burns my finger severely" zone of the temperature ALL the time. One peculiar thing I notice is that fan sometimes stops despite the lava temperature of the gpu, and when it comes on, it's never above 3000 rpm (saw in speedfan), tried disconnecting the yellow cable to make fan spin at a full load ll the time, 0 effect. Pattern of stops-starts is the same, as if nothing happened.

So help me notebookreview, you're my only hope.

 

Have you tried checking GPU temperatures using GPU-z or HWMonitor? Also, is your laptop still under warranty?

 

aand some more things happened just now. Now as I try to install nvidia drivers, I get:

Windows has stopped this device because it has reported problems. (Code 43)

 

Temperatures should be listed on the "Sensors" tab in GPU-z.

 

aaaaand GPU-Z shows no temperature whatsoever.

 

Just clocks which, weirdly enough, are 0.

 

UPDATE (Not that this is a particularly popular thread, but still )

Before I said that I disconnected the yellow wire so the fan would work full throttle but it didn't, apparently it was a blue wire, now I can make it cool the system a bit, but crashes carry on just as they did before even with the "witches in a brass brazier" cold gpu heatsink. as it seems:

temperature is not the problem, it's the symptom.

So there is some problem that causes gpu to crash and overheat. And the fun stuff is that it doesn't happen in any game. Crashes occur in the windows while doing simple things like browsing etc.

 

Hmm, if you don't use your laptop on battery, maybe you can try disable nVidia PowerMiser.

 

Tried Powermizer manager, it said there were no powermizer registry entries in the first place, but it has the option to make them, so I enabled it - no effect, disabled it - still no effect on crashes.
