Oh one thing I was going to say about agp port vid cards.. Remember the worse the card the bigger the memory window you need and the better the smaller the window you need. I fix puters all the time and find say 64 meg cards given a window of 64 or bigger window size. That's wrong. It shoud be smaller. 16 meg would be enough for such a card. a 16 meg card may need 16 or better window size the better cards almost need none. So set the cards up right and avoid that glitch. I good agp card will not use any extra memory so big windows are a waste. It's there for poor cards not excellent cards, say 128 meg cards. I've personally never had that bug show up but haven't gone over a gig also. If you have problems though it's the vcache, nothing to do with windows. IT's AGP cards using some memory for themselves. So you have to set windows up so it does not overwrite Vcache and set your cards up proper so that the window size is really all it needs if any. That's in the bios. Try it with none and if it works then leave it that way if not make it bigger in 8 meg steps till it does work then stop. Regaurdless chances are the card will never use it.
