Are you sure your memory is seated properly?

Sometimes you need to put the RAM sticks in alternate slots as opposed to next to each other.

Yes but i only have one memory stick, it is a 1gb stick and i have tried it in different slots and still the same error beep codes.

What is the motherboard?
if you have 2 or 3 slots some motherboards will work all right,
 but if you have 4 slots they must be paired, one each in either first and third or  one each in the First and second, often the nearest pair to the CPU as a rull.
the motherboard manufacturer and spec name numbers would help us a lot.
