Some machines required specific types of 256M memory sticks. Companies like Crucial.com and Kingston get you the right stick but generics will only work in most, but not all machines.
NOTHING YOU DO WILL CHANGE THIS. You'll want to order a stick from Crucial or such for your machine. If you didn't plug it in proper, then that's another issue, but I take it you did that.
The BIOS must be current as well.
