Update: Jesper has released a free tool to check whether you will be affected by the “IntelPPM” problem, and mitigate this before installing the service pack. What a hero!

News around the Web indicates that some PCs are experiencing an endless reboot cycle after installing Windows XP SP3.

It appears that it mainly affects a small amount of AMD-based PCs, although I have seen reports that Intel-based PCs have some issues too. Do not do anything hasty! It is probably going to be relatively painless to fix the issue - so don’t go formatting your hard drive just yet (unless you fancy a clean install).

If this has happened to you, Jesper Johansson’s blog has a great write-up on some troubleshooting steps.

He also points out the Microsoft is offering free installation and troubleshooting support for SP3.
