I am having problems with my 9800gx2 setup, Whenever I enable quad sli I have tons of problems. Whenever quad sli is enabled(with nvidia control panel) and I boot my computer half the time I will get a no input signal. My computer starts to boot then beeps and a blue light will come on either of the cards inside the case. If my monitor is not plugged into the correct card(card which light turned blue) I will get no input signal, If it is in the correct one windows will start up and then begin to blink black and in and out multiple times only after windows is booted and loading my programs. The system becomes extremely touchy once the blinking starts blue screening or just giving the no input signal after the computer has been on for about a hour. Also under the nvidia control panel settings the card that oftens works the most(bottom card in case) has the setting to [enable multi-gpu mode] while the top card gives the option [enable quad-sli] . Here are my specs any help would be greatly appreciated.
