| 205433 | 2004-01-05 05:28:00 | on power up the case speaker sounds in constant short RAPID beeps like you get sometimes when you overload the keyboard buffer also the keyboard lights flash constantly. the system continues to boot the system doesn't respond to any key presses the fault occurs without a keyboard the fault occurs with any keyboard the power supply has been swapped with no change the memory is seated correctly the AGP is seated correctly the BIOS chip is seated correctly the System boots to Floppy with no key presses recognized the system is just over 1 year old any help would be appreciated |

| 205434 | 2004-01-05 06:14:00 | The beeping is the key piece of info. When you say "continuous short beeps" can you confirm that it goes on forever? Some BIOS's have 9 short beeps, 11 short beeps etc for different faults. If not continuous, the number is critical. |

| 205436 | 2004-01-05 07:33:00 | #1 guess is a bad power supply, but there are other possibilities. However if you can borrow a PSU to try it would be worthwhile. |

| 205437 | 2004-01-05 07:35:00 | Check that the heatsink is still mounted firmly on the CPU as well. AMI and Pheonix BIOS's can give this error for bad power supply and over-temperature. A temperature would go critical in a few seconds with no heat sink in contact with the CPU. |

| 205438 | 2004-01-05 09:06:00 | as in the original post i have replaced the PSU with no change. The fan is running and the heatsink is in contact with the CPU. I am suspecting motherboard fault nes pas? |

| 205439 | 2004-01-06 01:58:00 | The keyboard LEDs flashing "sort of" indicates that it is stuck in the keyboard controller self test. The beeps might be coming from that, too. That probably means that the main CPU is alive enough to start the POST. Are any other LEDs flicking? (disk detect, etc) Does the power switch "work"? (start the machine, stop the beeping when it goes into the weeds?) |
