I would agree on the video card issue,,, we use the g100/200 millenium vid cards at work,, they die if you sneeze on them,, and the driver updates that were supplied by matrox, caused even more of them to die,,
to say that you used the card up until """" , is great, but how was it stored,, where was it sitting,, etc,, these cards are very very CRAPPY,,
if you can afford it,, go to your local PC swap shop and pick up a cheap vid card,, either to use,, or to test the problem,,
or,, take your card and put it in another pc,, ,,
check it out,,
cheers,
