Hello all,
I have a Sony VAIO FS760/W with a 6400go in it. It has 32MB of dedicated memory, and 96 turbocache.
Anyway, when I play relatively intensive games such as CS, CS:S, and CnC Generals for a while, the video freezes, the sound repeats, and I get the blue screen of death. The error lists nvdisp.dll if memory serves me right, which means it is tied to the video card.
Upon further inspection, when riva tuner samples the GPU core temperature, it hovers between 60 and 80C. Everything is fine until the GPU hits 80C. At that temperature, it always does what I described above. It seems strange that it does this at such a discrete value, though; it doesn't happen at 79C, for instance. Perhaps there is some sort of thermal protection in the drivers or on the hardware itself?
Note that I don't run any unnecessary software in the background. All I have in my tray is trillian, WLAN, LAN, audio, and the battery symbol. I generally have over 700MB free in task manager as well. I check for spy ware regularly too, and take measures against it using adblock and NoScript in Firefox. These seem to help a lot. I have also checked to make sure none of the vents are blocked; the laptop always sits on a flat surface such as a table while gaming.
I have the fan set so it is always on within the drivers. I've also tried under clocking the card 100mhz and changing the Powermizer setting to balanced. This causes a performance hit, and gives me more time before the system freezes and such, but doesn't fix the problem. It still hits 80C.
Does anyone have a clue how to fix this? The system is reasonably new (under a year old) and it has done this since the first month, so I doubt it is dust. I am hesitant to apply different thermal paste to the GPU cooler and such too, since the system is under warranty. I also want to avoid sending the system in since I use it for school and my desktop is currently down due to a w/c project.
Thanks a ton for any help.
