I have just bought 128MB of RAM for my PC, I've installed in it, but it is not registering on my system. Can anyone please help me get this resolved?

Many Thanks

Gary.

Please provide some information.

What is the Make/Model of your MB
What, if any, memory existed before you added this and what was it
What is the Make/Model of the memory you just bought.

Thanks!

Are you sure that the memory is seated firmly into the slot? Sometimes, you can get one end clicked in and not realise that the other end is sticking out slightly.

Are you sure that the new memory is the same type as the old memory? Are they the same speed rating?
