I failed to answer your question about there being a slot for a new card. When I was initially on the phone with the HP tech. he informed me there was an additional slot. At that time I asked if I could upgrade to a better card since the pc was being sent in for repairs. You know....pay the difference and do it all at once. I was told no....that when I got my pc back, I could call them and they would talk us thru putting an additional card in. (they would only fix the problem and do nothing else) We agreed we would wait and see what everyone recommends for cards before buying and installing.
So here we are..........
