I went to compaq.com, put in your model number and a few clicks landed at http://h10025.www1.hp.com/ewfrf/wc/softwareList?os=228&lc=en&dlc=en&cc=us&product=3184154&lang=en
It looks like the drivers are there for you.
I reinstalled windows XP, but now I can't open internet, it says that you need network drivers. I can't find that driver on manufacture's website. I am using Compaq SR1920NX desktop. Can anyone please help me resolve this problem. I appreciate your time.
