Built By Ati 9800pro 128mb in OCC Market Place Posted March 22, 2004 I think I just fixed mine. Time and heat had slowly warped the car to the point where it was not seating properly. It was so subtile that it would take about 30mins for the card to warm up enough to the point where it would distort enough to loose contact. (Signs of this were also evident in odd fluctuations of my rail voltages, btw. it was mainly the +12v rail that was giving the hint...) Ok, here is my point: monitor -everything- and maybe you will get a hint about the problems.
