  • Cold boot only on my new board (Asus P4T-E, bios 1005) I experienced the normal 1 beep and then 5 seconds later, 3 short beeps and then my system went into sleep mode. Changing the Suspend Mode to off OR increasing the # of seconds to enter suspend from default cured the problem.
  • Award BIOS 6.00PG/Asus P4T-E: 4 long beeps when turning on your system might indicate yout CPU fan is either damaged ot running to slow. Check your CPU fan. Clean or replace it with a new one.
  • Award BIOS 4.51PG/Soyo SY-6BB: A repeating high/low beeping. This is due to excess heat alarm. Solution: Change the settings in the BIOS or add/replace CPU fan.
  • Award BIOS/Asus A7V133: Check "Fan Check Beeping" under the "Power Management" options in the BIOS.
  • Award BIOS 6.00/Abit KR7A-133: One low pitched tone for every 5 seconds, over and over. System boots fine, but will not reboot from a warm boot. The system will reboot from a cold boot though. Check the fan speed in the BIOS and change it to a higher speed.
  • Award BIOS 4.51PG/Gigabyte GA-BX2000: Five short beeps sound when the main BIOS is corrupted and the spare BIOS has to be loaded as only choice for successful boot.
