I just built a PC and it just makes 1 long and 2 short beeps. I'm pretty sure it's not the graphics card because it is working fine with all fans on and pcie ports work. I tried both ports for graphics card and they work the same. I think it's the RAM.

My specs:

  • Motherboard-Asus M5A97 LE R2.0
  • Graphics Card-Asus Radeon HD 7870 Direct CU II
  • RAM-Corsair Vengeance LP 8 GB 1 Stick Black Version
  • Processor- AMD FX Black Version
  • Power Supply- EVGA 500B 500W Bronze
  • And a SATA Hard Drive

Seeing that asus's website says 1 long beep, 2 short beeps is a memory issue, I'd say you're right.

Go here to see compatible RAM for that board.
