...including two or three HP dv6000 series computers. (By the way, the primary problems were NOT with Intel processors but with AMD processors on HP/Compaq computers.) The key to getting Service Pack 3 to install correctly on Windows XP is to prepare the computer BEFORE attempting the install. Please follow the steps below:
First, do a complete system clean up like this:

Next, instead of installing SP3 from the Windows Update site, (especially since many have problems with the Windows Update installation of SP3) download the FULL SP2 installer from the link below and use it to install SP2. (It's a large file, about 300+ MB, so you'll need a broadband connection to download it.) Save a copy to a CD if you have a CD burner.

Now click on Start-All Programs-Accessories-System Tools-Disk Clean Up. Once that screen loads, click on the ''More Options'' tab, then in the ''System Restore'' section, click on the ''Clean Up'' tab to remove all but the most recent Restore Point. Choose ''Yes, when it asks: ''Are You Sure?''
After following all the procedures above, run Error Checking/Chkdsk and Defrag to optimize the hard drive:

After you've done all this, restart your computer, then disable all background programs, including your antivirus, then install Service Pack 3 from the downloaded installer file from above. Once that's done, restart the computer then visit the Windows Update site to see if you can use it correctly. If not, then perform the manual updates I suggested earlier.
Hope this helps.
