Unknown error My pc is over 5 years, few days ago, i have a unknown error. Once it's plug to power cable, it's starts to give few seconds continous short loud beeps, then continous (endless loops) of silent short beeps before i even press the power on button. Also, the Power Led is flashing faster than usual including the Power on button keep flashing green. After my power unit died out, i then got a new power supply, but still got the same problem. Even a new Hard drive, still a problem... My CPU and new Power Unit is working perfectly but i still can't find what's the problem is. I'm not even sure what's BIOS my system is using...

i don't think i need to replace my memory since i replace it 4 times just then...

i don't know where's the video card is... ( i think i don't have one)

i just switch around 2 of my DDR RAM...

cooling fan is on.

didn't try remove all unnecessary components yet
which i try to do it later on, using my sibling's laptop atm.

ok,

i try stick in 1 RAM at a time, and also in different slot, then done the same with other RAM, but still the same result.

also i try with remove hard drive, unnecesary components still have the same problem.

thought this might be useful:
i played online game when it's nearly midnight, then all the sudden, it shutdown unexpected and restart itself then it give this unknown error.... i unplug the plug taht lead to power cable since it won't stop with the same beep sounds and it won't shutdown. plug it again, still the same problem, then 3rd time the system stop, due to the power unit stop working (since it is very old using it over 5 years~).

Then get a new power unit which is 450 watts one, since my power unit was 250 watts,
then i thought a while ago just yesterday night, does it happen using 20 pins or 24 pins? since it's does still work for my system but still have the same error.

After i try with new power unit, i brought a new hard drive fixed perfectly and i don't see anything wrong with the new hard drive at all...
