This happened to my Dell Poweredge 400sc after 4 yrs of use.
It turned out that some capacitors on the motherboard were blown. I took them out and soldered some new ones on and it worked.
Look at the caps around the CPU. They are tall and cylindrical-shaped. There is an X mark pressed on the top of the component; this is for allowing the cap to break and drain slowly when it gets too hot inside. If you see leaks or you see the top bulges on the "X", the cap is bad.
If this is not the problem, it could be that the power supply can no longer support (being too old?) the current the system is drawing. In this case, take off everything, the extra hard drives, the old modem, the sound card, etc, and try the bare minimum system and see if it works. |
