    My Computer Beeps on Startup

    Issue:

    Your computer's Intel motherboard may produce beeping sounds as a means of communicating there is some type of failure at boot up.


    Resolution:

    If you are getting 1, 2, or 3 beeps that indicates a memory failure. 4 beeps indicate the timer is not operational. 5 or 7 beeps indicate a processor error. 6 beeps indicate a possible keyboard failure. 8 beeps indicate a graphics card failure. 10 beeps indicate CMOS errors. 11 beeps indicate that cache memory is bad.

    • 1, 2, or 3 beeps:
    • Reseat the memory. Make sure that the contacts on the memory and the socket are clean. Try removing one slot of memory modules at a time. Try using memory modules from the same manufacturer with the same part number and speed. Try using known good memory in the system. If the steps above do not resolve the problem, the desktop board may be defective. Try a different desktop board.
    • 4 beeps:
    • The motherboard may need to be replaced.
    • 5 or 7 beeps:
    • Check if the processor is seated properly. Reseat the processor and make sure that all the heatsink stands are properly secured in place. Try a different processor. If nothing helps the motherboard may be bad and needs to be replaced.
    • 6 beeps :
    • Try connecting a different keyboard.
    • 8 beeps:
    • Try a different Video Card or replace the motherboard (in cases when onboard graphics is used)
    • 9 beeps:
    • Flash the system BIOS or try a different motherboard.
    • 10 beeps:
    • The motherboard needs to be replaced.
    • 11 beeps:
    • Try a different processor or motherboard.
