Just bought a new pc to replace my plodding dell, it is the aldi medion Akoya P4340 MEDION UK as with past computers I wanted to put in the maximum ram, it came with 4gb I went on the crucial site and they recomended 2gb each in the vacant ports, I have learned since that Vista 32bit will only reconise 4gb of the 8gb installed, having said this I immediatly noticed a significant increase in speed when browsing web pages after installing the extra memory? Also the pc comes with an extra version of Vista 64bit not installed, what problems would I have if I attempted to install this i.e drivers etc. Thanks

Have to bear with me can fumble my way round pc but far from proficient
