Boot to Safe Mode by pressing F8 during boot as soon as you see the Manufacturers logo appear, earlier if that doesn't take.

Do a System Restore to before the failed SP3 install.

Click on Start, All Programs, Accessories, System Tools, System Restore. Pick a date before the SP3 install.

Download the Windows XP Service Pack 3 Network Installation Package for IT Professionals and Developers

Install from the downloaded file by double clicking on it. I've always had better success using it rather than via Windows Update.
