Can my computer run a 64-bit version of Windows?
To run a 64-bit version of Windows, your computer must have a 64-bit processor. To take advantage of the additional capability to utilize memory on 64-bit versions of Windows Vista, you should have at least 4 GB of RAM installed on your computer.
Additionally, you will need to make sure that you have 64-bit drivers for your hardware and that your programs will run in a 64-bit Windows environment. Device drivers that are 32-bit do not work on computers running 64-bit versions of Windows. If you are trying to install hardware that only has 32-bit drivers available, that hardware will not work correctly on 64-bit versions of Windows. Also, programs that try to install 32-bit device drivers on 64-bit versions of Windows will encounter errors. For information about updating drivers and troubleshooting issues with device drivers for 64-bit versions of Windows, contact the manufacturer of the hardware or software.

To find your computer's processor speed, do the following:
1.  Open System by clicking the Start button , clicking Control Panel, clicking System and Maintenance, and then clicking System.
2.  Under System, you can view the processor type and speed.
