this driver works on my HP zt3349cl Don't let them tell you that you can't use Windows 7. I had the same problem but kept on looking and found the right drivers. This is the one I am using now and works great and I only have 32mb on my card 6.14.10.6512 You have to go through some hoops to get it to work but look on the net and you will find all the details-sorry I don't remember where I found it. Try this too VGA_XP_2K_060102
