OK this problem has been occuring for a long time now, I just never addressed it. I have a MSI K7 Master a nvidia 64mb Geforce4. Out of the blue, my system would freeze for 45sec-1min then the screen would become 8 bit in the lowest resolution. It said that the vid-card has problem. But I've tried switching with 2 other vid cards and it still occurs. I updated to the newest nvidia drivers and it still happens. I reinstall windows, and it still happens. Any1 have any ideas? thanks
