I found that my computer run slow,sometimes hang when i open many program.the screen looks slowly.
someone suggest me to upgrade my memory.currently my memory is 128MB.I found that DELL 4500S use PC2100 DDR.
if i want to upgrade it,am i need to buy the same PC2100.can i use other than PC2100?for example PC2700?i need a 256MB memory.
what is the different,if i buy it directly from DELL or the hardware shop?
is the manufacturer same?
Can i just insert my new memory card into another the slot n never take out the old one?
anyone can help me?
