Sorry, not an IT Pro, just a guy who knows enough to be dangerous. I would appreciate someone giving me a clue as to what is wrong with my system.

No power, period. Yes it's plugged in. Naturally, I figured the power supply went south, so I replaced it. Didn't work. I replaced the battery on the Motherboard (don't ask why...), changed outlets, checked connections to the power switch on the front and still, no power (the fan on the PS doesn't come on, no lights, just deader than a door-nail).

Clues??

Assuming you installed the correct power supply, and assuming it's securly plugged into the motherboard, and assuming the power switch from the case is connected correctly, and assuming you turned on the black switch on the back of the new power supply, then start removing components one at a time. For example, remove the soud card, and try it again. Remove the NIC, and try it again, Remove the graphics card......

A bad component could cause that result. If you've removed enough and are downto the motherboard only, then the board is fried.

Find where the switch from the case goes onto the motherboard jumper and short it momentarily. If it doesn't come on, then the off\on\sleep circuit in the board is probably toast. Just to make sure, hardware reset the BIOS to defaults by connecting the short jumper... it'll tell you how in the manual or online.

Also, don't kill me for stating the obvious, but in addition to plugging it in, is there an additional switch built into the power supply? If so, make sure it is on too. :)

The switch isn't really "the" switch anymore on most modern systems. It merely sends a signal for the embedded switch to turn on.

this could be caused by a faulty or dead graphic card (if you use one)
also bad or broken memory.

your cpu could be broke.

what you need to do is try the board with a differnet graphic card, then diff memory then cpu, you need to go through elimination till you find the culprit.

also the motherboard may very well be broke mate, hope not but a possability?

also when you changed your PSU did you make sure that the conections for the motherborad were conected correctly, with newer cpus like the P4 intel the motherboards have an extra conection you need to plug in from the power supply.

either way mate hope you found your problem and got it fixxed
