ksdh,
Press F10 and go through the BIOS setup screens and see if there are settings that need to be changed.
Also go to the HP site and download the Machine Drivers and Chipset Driver including the latest Bios update and the installation utility.
Appears all the XP drivers are posted.
Update your Bios if needed.
Just ENSURE to get the correct ones for your particular (specific Configuration) machine model. Look on the back panel of your machine.
May NOT need to install but a couple as XP3 appears to have most of them in it.
Look in Device Manager and see if you have any Devices with a red X or yellow ! mark.
ALSO be sure to check the hidden devices on the drop down menu.
Most forget to do this !!
Go to MS Update Site and download updates.
Many times there will be a updated HW driver included for installation after your machine is scanned.
Regards,
Rick P.
