My CPU Usage graph in Task Manager reflects 2 graphs...double-click on the left graph and it will show both cores.

Did you install the OS with the new dual core CPU, or swap CPUs with the same install?

Read this thread, it will save some typing and questions.

XP Home could be "wonky" when it came to multicore support. The link I posted refers to XP Pro I think, but it applies to XP Home as well. Good luck.

You have to replace the hal.dll and ntoskrnl.exe to enable multi core support. Long story short, a repair install is the easiest way to do this. Even better a fresh install. There is another way to do it but it is a PITA.
