وده خلاصه الحل
Ok, i had this issue and serched 2 weeks trying to resolve it. I tried different cards, different OS's and versions (x86 and x64) new mobo, new PSU, memory you name it, nothing fixed it. BUT guess what, I have the solution and it fixed my system. Vista and Win7 use a feature called TDR. TDR baically gives your GPU 2 seconds to process what it is doin and display it on your monitor. If it fails to do so in 2 secondsyou get the cool flash on the screen and the dreaded error message. Heres how to correc the false positive....
1. Open REGEDIT
2. Using Windows 7, go to HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\Gr aphicsDrivers
3. 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.
I did this myself, and now im back up and running at full speed. I can watch my movies and play all my games again! Cheers!
