Do NOT install the new XP Service Pack 3 for on any computer using an AMD CPU. You end up in a perpetual reboot cycle.
Microsoft KNEW this was an issue and released it anyway with NO warning!
After my system was trashed I went through Google and found hundreds of people who had the same problem. A lot of them were people who had HP computers, but it apparently hits just about all AMD machines. These complaits date back to the beta release and it has never been fixed. I tried several of the fixes posted and not a single one has worked so far.
I have just deleted programs to clear space and I am installing XP Pro Black Edition on the new space.
Spread the word to those who might have AMD computers and warn them to avoid SP3!
I got this from another site and thought I'd pass it along.

Thank you for telling us! My husband and I have both AMD CPUs (old ones at that) and after installing SP2 the first time around, I had to wipe my C: drive and to set it up from scratch with my backup data on my alternate drive. (Luckily, I had just completely wiped both drives three months before after installing XP on my system so I didn't lose much data). But still ... wow, I'll spread the word.
