Dual core only shows as single CPU

Hi

After problems with the driver for the onboard Ethernet on Asus P5K I have
opted for a standalone Ethernet card. I have also reinstalled VISTA
Ultimatein conjunction with this problem .

After reinstall the experience index has dropped from 5.3 to 4.4 with the
CPU giving a lower score than previously. The task manager only shows one
pane for CPU performance in place of the 2 shown previously. The processor is
reported correctly as Intel core 2 CPU 6600 at 2.40 GHz in Control
Panel\System and Maintenance\System. Can the problem be BIOS related?

If the hyperthreading option in your BIOS is disabled, you will
only see one core. That is my experience with a Gigabyte motherboard.
I don't have any experience with ASUS but there are only about three
companies that write BIOSs.

A quick check:
Right click computer
Properties
Advanced system settings
Environment Variables
Under System variables there should be an entry 'number of processors'. If
it shows 1 you might try changing it to 2. However I suspect that if it sees
only one from BIOS then you will not be able to change it.

In my BIOS (Dell XPS410), Intel Core 2 Duo CPU E6600 @2.40 GHz, I have
Multiple Core Capable: Yes (Dual)
Hyperthreading Capable: No
