What computer? Which operating system? How old is the computer? How many beeps? Which motherboard?

Tried reseating the motherboard, checking the power supply plugs, reseating RAM, replacing RAM, etc.

Tried replacing the power supply?

Tried putting a NEW CMOS battery?

Hope this helps and let us know more.

The BIOS performs a power-on self-test (POST) (a built-in diagnostic program that checks system hardware to ensure that everything is present and functioning properly, before the BIOS begins the actual boot), a test which is used to ensure a system is functioning properly. When a problem is identified, the BIOS will normally produce an error message. In some cases, since a problem may be detected so early that the BIOS cannot even access the video card to print the message, a series of beeping pattern will be produced on the speaker to tell a user what the problem is. The exact meaning of the beep codes depends on the type and version of BIOS. A site to check for BIOS Post Codes is "BIOS Central" -- please note the box upper right-hand side identifiying the system BIOS used on the system -- this you must know.

Note: A single beep during the boot process -- usually right before the BIOS startup screen is displayed -- is normal and does not indicate a failure as long as the boot process continues.
