Sorry, i wont speak up again. BUT...
* He needs more leds connected. (read post)
* He asked for a 3 Volt resistor.
Since there are no such thing, the easiest to do are leds in serial. Power coming from the computer psu would give 5V, that makes 2,5 V for each led.
* He dont have to mess with calculators or make a fool of himself asking for a 3 Volt resistor.
* It will work.
