Award BIOS Beep Codes

  • 1long, 2 short – Video adapter error (Either video adapter is bad or is not seated properly. Also, check to ensure the monitor cable is connected properly.)
  • Repeating (endless loop) – Memory error (Check for improperly seated or missing memory.)
  • 1long, 3short – No video card or bad video RAM (Reseat or replace the video card.)
  • High frequency beeeps while running – Overheated CPU (Check the CPU fan for proper operation. Check the case for proper air flow.)
  • Repeating High/Low – CPU (Either the CPU is not seated properly or the CPU is damaged. May also be due to excess heat. Check the CPU fan or BIOS settings for proper fan speed.)
