5 beeps 3 times and 5 blinks on front red LED until I remove the power cord

[horaciojg]

When I plug in the power cord the power green LED goes ON and the HDD green LED goes ON and then OFF. The same with the CD drive power LED. All the fans are ON, but after a few seconds the CPU sound with 5 beeps with a secuence of 5 times. At the same time the power front LED goes to red blinking 5 times. After the beeps goes off, the front LED continues blinking 5 times with pause between each sequence until I unpluged power cord.

I changed the 4 DIMM modules and nothing happen. I also left the video board only connected removing the rest of PCI cards and the problem is the same.

Can somebody help me?

Hi I changed the 4 DIMM memories and the problem is still there.

I also change the video card and the fail is the same.

I think the problem is in the mother board.
Do you have any idea if I can solved this fail without change the mother board.?

I did not manage to identify the sequence of your explanation, compared to what is indicated
it just seemed to me that there was a reference with the memory!
did you try each slot one by one with each module?
if not, sorry, if the motherboard, it may need to be replaced, but try to see a professional, he can test different elements
