Right-click on My-computer and hit properties, and under the heading "Computer" see if it has registered the memory in there, i.e it should say "1GB of RAM" or your 1GB plus whatever was in there in the first place. If it still only says 192mb RAM, you may have to fiddle with the bios... I'd google it as thats all i do EDIT - Oh and before you play with anything in the bios, google it all first, if you change the wrong thing the laptop may not function properly...
