Replaced AMD 3200 w/ Intel e6600, xp shows 1 core?

[snedecor]

I had a setup on wife's computer: ECS MB, Athlon XP 3200+, Windows XP Pro.

I decided to try to upgrade her computer.

I got a new MB (ECS) Intel e6600, 2GB DDR2, Diamond x1300 (she's not a gamer). I did not want to re-load windows unless I had to.

Windows booted with the new system, and I installed software for the MB, the video card, etc. System runs fine, all old programs, peripherals, etc. work.

However, XP only shows one processor in several areas: 1) Task Manager, 2) Speedfan, 3) CPU-Z.

How do I get existing install of XP to recognize/support the dual core?

Sorry if this is a newbie question, I tried searching.....

first back up all data then do clean install windows xp it will recongize two cores.

Never mind. I figured out how to do it. Piece of cake.

Repair install will do it.

You probably want to do at least a repair install when changing that many components.

You need to change the "Computer" driver to "ACPI Multiprocessor PC".
