I have successfully installed a 1Gb upgrade to my PC. General programs are now much quicker than before and the PC recognizes the new RAM. My internet connection is however extremely slow - will not even load new emails. I can search but visiting websites is a nightmare - takes forever to get to page 1. May be nothing to do with the upgrade - which clearly is working and recognized - but is there something that I am not seeing? Have run virus checks etc and found nothing. I am running windows XP SP3 and AVG internet security suite. Have also managed to download Firefox, and this is also impossibly slow.
