CORE 2 DUO: Only 1 processor working RRS feed

  • Question

  • The machine i have came with XP Professional. The processor i have is Core 2 Duo with 2 GB RAM, VGA crad etc. With Windows XP Professional it works fine, but when i installed Vista (64 bit) Business it only shows as one processor working. No error messages are displayed. I have checked in the bios and both processors are enabled, and in device manager only 1 processor is showing. When i go into Task Manager only one processor shows. How do i enable the second processor in Vista, even though it works fine in XP Professional?
