Question about Intel Motherboard
The first thing I would do is to make sure your power supply is good. I have found that sometimes they will make some of the lights come on, but they may have 12V and not 5V or whatever. I bought a small thing you plug the power supplies into, and then the lights light up to show you if the power supply is supplying what it should. Once you are sure the power supply is good, (don't assume) if they still don't work, I would visually check the boards. I have found many times the small capacitors go bad. After replacing them, the boards worked fine. Usually they will have the top cracked open or bubbled up. If you are up on electronics, as I guess you are if you know how to read a schematic, soldering in new ones is a simple matter. I also remove the CPU, clean the bottom surface off, and put a small amount of CPU grease on and reinstall the CPU. Be sure to check all the pins, as they are pretty small and easy to bend one over.
