I recently changed from a X1600 Pro to a GTX 650 Ti and today I went ahead and turned on Speedfan. It detects I can control up to 4. Usually I put it to 60%, all of them. Today I went copy pasting but when I got to the last one and put 60%, my display suddenly turned off, the led light telling me if the display is on/off started blinking like it was receiving no input. Since it was odd, I alt+F4 (I had SpeedFan selected) and it quit the program and speeds went back to normal. Nonetheless, my display remained like this and I had to press the reset button.
Booting Windows 7 back up, it says a BSOD happened.
What could be the issue here? Im scared of turning the fans down again in case it damages the new card...
