      AMI BIOS Beep Codes:

      1 short: DRAM refresh failure:
      The programmable interrupt timer or programmable interrupt controller has probably failed

      2 short: Memory parity error:
      A memory parity error has occurred in the first 64K of RAM.? The RAM IC is probably bad

      3 short: Base 64K memory failure:
      A memory failure has occurred in the first 64K of RAM.? The RAM IC is probably bad

      4 short: System timer failure:
      The system clock/timer IC has failed or there is a memory error in the first bank of memory

      5 short: Processor error:
      The system CPU has failed

      6 short: Gate A20 failure:
      The keyboard controller IC has failed, which is not allowing Gate A20 to switch the processor to protected mode. Replace the keyboard controller

      7 short: Virtual mode processor exception error:
      The CPU has generated an exception error because of a fault in the CPU or motherboard circuitry

      8 short: Display memory read/write error:
      The system video adapter is missing or defective

      9 short: ROM checksum error:
      The contents of the system BIOS ROM does not match the expected checksum value.? The BIOS ROM is probably defective and should be replaced

      10 short: CMOS shutdown register read/write error:
      The shutdown for the CMOS has failed

      11 short: Cache error:
      The L2 cache is faulty

      1 long, 2 short: Failure in video system:
      An error was encountered in the video BIOS ROM, or a horizontal retrace failure has been encountered

      1 long, 3 short: Memory test failure:
      A fault has been detected in memory above 64KB

      1 long, 8 short: Display test failure:
      The video adapter is either missing or defective

      2 short: POST Failure:
      One of the hardware testa have failed

      1 long:
      POST has passed all tests.

      It sounds like your graphic card is/has gone or is giving you some trouble here. Take it out and get another one to test.
      Hope all goes well.
