I'm having an unsual (as far as I know) problem with my two Nvidia 9600GT (Sli) cards and my Samsung T220 Monitor. When I lswitch my computer on my monitor loses signal shortly after the Xp Pro loading bar appears. I remove the connector from the back of the computer, push it back in and Windows XP displays with no problem. I've patched Windows, downloaded New drivers for both graphics cards and for the Samsung but the problem persists.
