If not download from the HP official site and run the driver to be installed. If there is no result as the audio does not work there can be errors in the OS or a possible hardware issue.

Try resetting the BIOS, if the date is not correct the BIOS battery will need to be replaced.

The most likely cause is your hard drive has stopped being detected for some reason. You would need to go into the CMOS setup utility and check and see if the drive is listed there. Usually there is a shortcut key you push like F1, F2, Del, F12 (it varies from computer to computer). Start trying these keys right after powering on the PC (within one or two seconds). The actual screens also vary from PC to PC, making it difficult to describe further clarification on what these will look like.

If you're comfortable with opening your PC you can check and make sure the power and data cables are securely connected.

Sometimes inexplicably the simple act of blowing all the dust and other crud out of a PC helps with this. If you haven't done that for a while...stranger things have happened.

If all else fails you may have to buy a new hard drive and re-install your OS. Before that I would recommend taking the PC to someone who can look at it in person and really determine the issue.

CD Drives normally have a small pinhole which you can trigger to manually eject the drive. Do this:

1. Turn off your computer
2. Get a paper clip thin enough to fit into this pinhole at the front of the CD drive.
3. Insert the paper clip into the pinhole until you see the drive eject. You may need to push in the paperclip around 1 inch or so.
