|99.9% of the time if it beeps it's a memory card issue. |
Depending on your motherboard's configuration, if you have multiple sticks and multiple slots then take out the sticks and try them in each slot 1 by 1. If both sticks fail in the same slots, you've got a bum slot. If only 1 stick is having problems in 1 or both slots, and the other one works fine in both, you've got a bad stick.
If you've only got 1 stick and 1 slot, then it's easier - try a different memory stick in the slot and if it works you've got a bad stick. If it doesn't work with a new stick, you need a new motherboard.
