Award BIOS:
| Beeps | Error Message | Description | |||
| 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. |
Submissions:
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.

Phoenix ISA/MCA/EISA BIOS:
The beep codes are represented in the number of beeps. E.g. 1-1-2 would mean 1 beep, a pause, 1 beep, a pause, and 2 beeps.
With a Dell computer, a 1-2 beep code can also indicate that a bootable add-in card is installed but no boot device is attached. For example, in you insert a Promise Ultra-66 card but do not connect a hard drive to it, you will get the beep code. I verified this with a SIIG (crap -- avoid like the plague) Ultra-66 card, and then confirmed the results with Dell.
