"Display driver xxxxx stopped responding and was recovered"

Timeout Detection & Recovery (TDR) = "Display Driver Stopped Responding and was Recovered" is a useful feature that started in Vista and is also in W7 that allows the OS to try and recover from a video timeout so that the system does not crash to a bluescreen. Symptoms included a screen flash with the TDR message appearing one or more times or the screen blinking out to black. If the system cannot recover it will crash (Stop Error 116 typical). The issue is that the video card is not responding as expected.

The first things to look for in a TDR failure is the drivers and temperatures.

• Download Speccy and post a Screenshot of the summary window, one at idle and another while putting load on the PC using Prime95 for the CPU side and Furmark for the GPU.
• Download an older release of the drivers. >310.90<, Follow the steps detailed below:
