Timeout causes graphics card to fail. Occasionally, when on a web page with pictures/video/flash, the screen will "freeze" and have some random colored pixels appear or sometimes it will just go black. Sometimes when this happens the whole system will remain locked. Other times it will recover and I will get a notification balloon saying the the graphics driver has stopped and recovered from an error. I've looked for answers to this on the web and I have seen reference to it being caused by a Windows timeout waiting for a response from the video card. Is there a way to modify (extend) the timeout value to try to prevent this? I have the latest drivers. In my case the graphics card is NVidea Quadro FX 1800M on a Dell Precision M4500 notebook (8G RAM). OS: Win 7 Enterprise 64-bit.
