Posted about this a few weeks ago, and thought I had solved the problem but it has reared its ugly head again. My system has been experiencing random shut downs/restarts while under load. Originally thought it was a cooling issue as my 6950 had been set to manual fan control and was running pretty hot. After increasing the fan speed and lowering the temps, the problem was reduced dramatically (system crash and reboot happens far less frequently now), but is still happening every once in a while. The error log in Windows 7 describes it as either a power supply or cooling issue, but my GPU never runs above 53 C anymore so it cant be a cooling problem. The strange thing is, the higher I set my GPU fan speed, the less frequently this issue occurs - leading me to believe its not a power supply issue either (Doesn't increased fan speed = increased power usage?). Any ideas/suggestions greatly appreciated
