Desperately Need Help with P-7805u Problem

Purchased about a month ago refurbished, and have had a problem ever since. While the battery is fully charged or almost fully charged, and the computer is plugged in, I freeze about 10 minutes into any game I'm playing (Fallout 3, Far Cry, Crysis). If I play on solely battery power, everything works fine until the battery is drained. I tried drivers 185.81 and 185.85 (currently installed), and the problem still exists. I've eliminated overheating as a cause because the problem still occurs in furmark, and the temps were at 50C cpu and 70C GPU max. I set up rivatune to monitor hardware and log it while I played a game, and this was the result after the game froze.




All the clock speeds jumped to their maximum settings which i had set to default factory settings using the nvidia control panel. I read somewhere that the default memory clock speed is 900, however whenever I set it to default it is 799, can anyone confirm that?

Here is my control Panel


I'm running vista 64 ultimate. The problem was happening from day 1, so I thought wiping the computer clean and reinstalling vista could fix it, it didn't.

I've spent a lot of my time researching this, and I've found posts on other forums of people with similar problems, but have yet to come across a solution. Any help would be greatly appreciated.

 

Your clocks are correct. You may need to re-install the OS.

 

Thanks for the reply, but I already tried that and it didn't fix it.

 

my cousin's p-7811 has the freeze problem as well. i fixed it for him by turned off the powermizer feature.

Turning off powermizer did not work.

I did however monitor that my gpu clocks would go to max settings and sit there while i was plugged in, so i unplugged and watched the clocks drop to
Core: 400
Memory: 300
Shader: 800

So I set those to be the settings in the nvidia control panel, and that seems to have worked. Not exactly the perfect fix though since i have to severely underclock. If anyone has any better ideas, please let me know. Thanks.

 

You eliminated 1) Heat 2) OS. The only other option I would see is the gpu. Its either that or the motherboard. might be worth the 65 bucks to have someone check it depending on how much the video card cost.

 

Try GPU-Z and see if the speeds match what nvidia says. Cause gateway may have set up a different than stock GPU throttling if it was sent in for overheating.

Try Speedfan to make fan constantly on.
