My 2 Yr old Celeron PC powers-up immediately power is turned on, without pressing ON button - I hear ONE extended BEEP - Soon after I get continuous BEEPS until I press power button to turn OFF - No activity on monitor. I have tried swopping PSU + RAM + Graphics Card + CMOS Battery. I also tried clearing CMOS Jumper (JBIOS). Does it mean Motherboard failure? Any suggestions appreciated. Thank you.

It could be the processor that is dead. If you have swapped out the graphics card but still don't get anything on your monitor...I am thinking it is the processor.

Thank you for your suggestion, but it appears that the motherboard is the problem, and will be replaced.

Rob,

That long BEEP followed by continuous BEEPS (long too) means a memory problem. It is defined as "DRAM refresh failure". Try replacing the RAM. Also test all the RAM slots one by one with the new RAM (the old RAM could be used to test the other slots too). If you don't get good results the problem is the motherboard (dead).

Good Luck

Jos?

Thank you for your suggestion but, I had already tried different RAM. It appears that the motherboard is the problem, and will be replaced.

Thank you for your suggestion. I had checked various beepcode sites for info, and it appears that the motherboard is the problem, and will be replaced.

There is nothing wrong with the processor.
If the CPU fails, the PC will not beep, because it is the CPU that generates the Beeps using the system timer chip.
I am assuming you have an Phoenix BIOS.
This is most likely a memory controller problem.
That this failure occured in the early middle part of the lifecycle of this PC means there is another problem also.
Sounds like insufficient airflow.
Also check for loose screws, and other debris, inside the PC that could cause a short circuit.
Get a magnifying glass and carefully check the Mother Board for damage.
If there is no damage, and the memory you swapped in is "Known Good", then thie chances are good that the memory controller has failed.
That chip is soldered onto the MB.
That means "change motherboard".
The other possibility is that, you have encountered the very very rare BIOS virus that causes these symptoms.
Hopefully, "Disable BIOS updates was selected in the BIOS".
Regards, Chris

Thank you for all your in-depth suggestions. It does appear that the motherboard is indeed the problem, and will be replaced.

the continous beep means that your mother board is not getting the correct juice from your powersupply. Try checking your powersupply or if you have a second chasis use that and see if the beep goes away.

Thank you for your suggestion but, I had already tried a different PSU, which made no difference. It appears that the motherboard is the problem, and will be replaced.
