I have a Gigabyte GA5-AX mother board with the Ali Aladin Chip set and 64 meg ram,CPU is AMD K6-2 500mhz. My video card is Power Color, nVida Riva TNT2 pro, with 32 meg ram.  Operating system is a stand alone (ienot networked)Windows NT4 build 1381, service pack 6a All drivers are the most up to date available.  From day 1 I have been experiencing random system freezes, ie suddenly nothing is happening. not even cursor blink.  There is some indication that the mother board continues to run, at least in part, as the power key on the keyboard will shut the machine down, even though the video is completely frozen.

Any help in determining what is causing this would be greately appreciated.  I am considering a different video card or mother board, but as yet don't know which to replace.
