I have had a great deal of problems with this issue. Most of the day I am playing or surfing the net and bam it blanks out. I do know when it is coming cause it freezes my comp a sec before it happens. The monitor light will stay green during this and the video card temp is a cool 57 degrees. I did also up date the monitor drivers to see if that would fix it. That failed so now here I am.
