Is it possible to downgrade from 14.04.1 64-bit to 32-bit as an old PC is having real trouble running 64-bit.

32bit and 64bit are classed as different CPU architecture. You will have to perform a clean install.

However if you just want to run 32bit programs you can install ia32-libs-multiarch to add 32bit support to the 64bit OS

sudo apt-get install ia32-libs-multiarch
