Hi, I have a sony vaio VGN AR41E that I use for music making. Im running win 7 32bit. Fortunately the laptop has dual HD so I have upgraded from 100Gb 5200rpm to 500Gb 7200, which gives me 1TB of space, which is plenty for what Im doing. As I cant upgrade processor ? i would like to upgrade memory, from 2Gb to 4Gb but the spec says 2Gb is the limit ? What are the chances of a upgrade working and not damaging anything ? Any suggestions welcome ?
