Yes you will be able to install a windows 7 64bit operating system the CPU is 64 bit compatible but you won't be able to use the drivers you currently have for your hardware you will have to download all the win7 64bit drivers for your hardware from http://support.dell.com/support/download... recommend you download all drivers for hardware first and store them on usb stick or burn to CD/DVD before you upgrade your operating system as you may not be able to get internet connectivity until you load the required drivers.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
