I suspect you got 32-bit Windows XP on your system. If so, then you can't use 64-bit drivers (and don't need them). Check the OS version by hitting Windows-Break. If you have a 64-bit OS installed, you should already have 64-bit drivers. Either way, you should not need to worry about it.

The dual cores should be active. Bring up task manager and see if it shows two CPUs in the performance tab.

Thanks Peter I have Windows XP Media Centre 2002 SP 2 but am waiting for Vista Hoe Premium. Why would I have 32 bit widnwos and not 64 as the processor is 64 bit. Are Dell short changing me :) Thanks Craig

No. you did not get shortchanged. Most people don't need a 64-bit OS. The main reason for getting a 64-bit OS is to address more than 4G of RAM.

Further, I have heard 64-bit Windows is a pain because many drivers are not available and it is not nearly as stable as 32-bit Windows. Personally, I would rather have stability.

The Pentium-D and Core 2 Duos are also 64-bit processors, but routinely come with 32-bit OS. I can dual boot to a 64-bit OS (e.g. Linux-64) if I like.

Eventually, all OS will be 64-bits.
