Step 5

One Beep: DRAM refresh failure
Two Beeps: Parity Error/parity circuit failure
Three Beeps: Base 64K memory failure
Four Beeps: System timer not operational
Five Beeps: Processor failure
Six Beeps: 8042 keyboard controller/gate A20
Seven Beeps: Processor exception interrupt error/virtual mode execution error
Eight Beeps: Display Memory read/write error
Nine Beeps: ROM Bios checksum error
Ten Beeps: CMOS shutdown register read/write error
Eleven Beeps: Cache memory bad--do not enable cache



(1)One Long Beep, (2)One Short Beep, (3)One Long Beep, (4)One Short Beep;
1-1-3 CMOS write/ read failure
1-1-4 RAM bios checksum error
1-2-1 Programmable inteval timer failure
1-2-2 DMA initialization failure
1-2-3 DMA page register write/read failure

1-3-1 RAM refresh verification failure
1-3-3 First 64K RAM chip or data failure, multi bit
1-3-4 first 64k odd/even logic failure
1-4-1 address line failure 64k of RAM

1-4-2 Parity first 64k of RAM
1-4-3 Fail safe timer failure

4-2-1 Timer tick failure
4-2-2 Shutdown test failure
4-2-3 Gate A20 failure
4-2-4 Unexpected interrupt in protected mode
4-3-1 RAM test address failure
4-3-2 Programmable interval timer channel 2 test failure
4-3-4 tome of the day clock failure
4-3-3 Interval timer channel 2 failure
4-4-1 Serial port test failure
4-4-2 Parallel port test failure
4-4-3 Math coprocessor failure


No Beeps: If all you hear is silence, and there is no image on the screen, check the power supply, next inspect motherboard for loose components, next eliminate the possibility of interference by a failed or improper set up CARDS--remove all CARDS except video card at the least the system should power up and wait for drive to time out(sounds a drive makes during start-up) then insert the CARDS one at a time , if the system hangs then you'll know when the last interference occurred thereby solving the problem. Don't remove chips that are malfunctioning if you don't know what your doing at least these are tips what your PC's problem before going to a qualified technicians.
