I would think the power supply is the most likely culprit, does it not say the rating? I assume that the 400FA means 400 watts and if it was working it might well have been working flat out, if so it would require much strain on it for the power to drop enough to effect the graphics.
Only other thing I can think of is the card is starting to fail but I think the power supply is most likely the fault. I'm sure the recommended power supply for the X1950 is at least a 450 watt and even at that I would say to be certain it was ok it would have to be a branded power supply.

I would get a better psu with 20a or better on the +12. there may be info at the ati graphic card forum at guru3d.com.
