I bought a new HP Compaq Presario 707TU Notebook few days back. To my surprise there was no driver CD comes with it. I installed Windows XP Professional Edition in it and couldn’t find the driver on HP’s website.  They have only provided the drivers for Windows Vista Operation System. Later, I found that there are so many people having the same issue.
Now the best part is that, today, I got all drivers for it. Thanks to HP Technical help desk. Here are the links to download the drivers. Please remember that these drivers are for window XP OS. You can find the driver for windows Vista on the HP website.
