It is possible that static discharge or a loose connection could manifest these symptoms as well. I would start by verifying that everything is properly and securely plugged into the motherboard. After that, make a complete visual inspection of the board looking for capacitors that are bubbling or distorting outwards on the top (capacitors are the cylindrical components on the board, usually with two leads anchoring it to the PCB). From there, you should find some way of testing your power supply. Either find another machine into which you can plug the PSU to see if it posts the board, or take it to your local computer repair shop, as they should have a device to test it. If your power supply tests alright, begin removing components from the board to see if you can get it to post. Remove PCI cards, sticks of RAM, IDE/SATA connectors, front panel and USB connectors. Everything. If you reach the end of this diagnostic process without a single post, chances are your board is FUBAR and you should replace it. Cheers, D
