What to Expect when replacing a motherboard and processor - P3 to P4?

I have a compaq 7000T p3 that I plan to upgrade - by replacing the motherboard -ASUS type and a P4 Hyper-Threading processor.  What issues/problems can I expect?  My system is currently running XP Pro, with SP2.

Would I have to reactivate - and get a new product key?  Would making a copy of the WPA.dbl files spare me some aggravation?

Replace Motherboard on a Windows XP System

Changing a Motherboard or Moving a Hard Drive with XP Installed
Hey  sta596526,

I just did the same thing with my pc about a week ago and I also did a drive migration for my girlfriend a month ago. The process should go pretty smoothly without incident. The only "issue" you should have to worry about is with XP sending you a whole mess of "found new hardware" messages the first time you boot theOS in its new home. But once the hardrive gets all nice and comfortable in its new shell, you should be straight.

As far as reactivating your key is concerned. I never had to do it myself but if you do run into that snag, this link may help:


Hope this helps

Made a mistake. the "328784" at the end of that link should be "328874" here it is:


please forgive my poor typing skills
