hi, i have premiere 6.5 running on an amd 3200xp with 1gig ddr 400 ram, and a radeon 9200 atlantis 256mb g/c. while editing, premiere, well, actually, there is no warning. the system just reboots. nothing in the error logs. any suggestions. the temp of the chip is usually steady at around 53-55 degrees, has gone as high as 57 in the last few day, but it has been warm.
