intel desktop board 01 e70931-403What motherboard do you have?
If it is a Asus one then one long beep followed by 3 short beeps usually means that no VGA/GPU was detected. have you connected the new card to extra power from the PSU? You can not run a GTX980 just from the motherboard it needs to be hooked up to the power supply with one or two 6-8 pin cables. If memory serves me right most of the GTX980 cards needed either 2X 6 pin cables or 1 X 6 pin+ 1X 8 pin connector depending on the model used.
