Some people reported got an error message when he using his computer: Display driver stopped responding and has recovered.
Sometimes, when this error message comes out, the computer will get hang for some minutes and then BSOD or reboots.Resolution:
It appears to be a graphic card driver issue, anyway. Vista and Win7 use a feature called TDR. TDR baically gives the GPU 2 seconds to process what it is doing and display it on your monitor. If it fails to do so in 2 seconds you get the cool flash on the screen and the dreaded error message. In some cases, the situation get relief by giving TDR more time by setting registry value1. Open REGEDIT2. Using Windows 7, go to HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\GraphicsDrivers3. Once there you will most likely have to create a new DWORD (32bit users) or QWORD (64bit users). Name it TdrDelay.4. Once created, change the value to 8. This will allow the GPU 8 seconds to respond instead of 2 seconds.More registry key explanations are here:http://www.microsoft.com/whdc/device/display/wddm_timeout.mspx Some customers fix the issue through they own ways, Below are the ways they use:1. Go to BIOS and set the CPU from 200hz to 180hz.2. Upgrade nforce motherboard driver.3. Upgrade NVIDIA driver to latest beta build.4. Change graphics card and maybe power supply.
After many weeks of Googling, going through 100 threads, trying many of the solutions (some of which being ridiculous like reformatting, replacing hardware, etc.), I found ONE POST that suggested what I can now confirm fixes this problem. Not "it hasn't happened yet, keeping my fingers crossed", but actually fixed.
Nvidia Control Panel -> 3D Settings -> Set PhysX configuration -> Select a Physx processor -> choose your graphics card instead of leaving it on auto-select.
problem still exists.....dude!
used regedit but still this happens.......also used physx setting changed same prob happening
