Try to remove all components all drives (hard drives, cd/dvd roms, floppy drives, etc), all additional cards (modem, video card, sound card etc), remove the memory. Just leave the motheboard, proc and power supply. Before disconnecting everything completely discharge power by holding down the power button while the computer is unplug from the power. It should clear the flea light on the motherboard.
Test it again with just the motherboard, processor and the power supply. If still no power then most likely it is the motherboard since you already put a known good power supply. Motherboard has higher failure rate than the processor. You can swap a known good processor if there is.
It may sound weird but check that the motherboard battery cell is charged (the CR2032 coin battery). Some motherboards wouldn't power on if the battery is completely empty. Also clear the system setup via the jumpers on the board. Try booting up with no graphic card installed and using the onboard graphics (if the board has a onboard GPU).
Oh thats easy.!. Well here we go: First you need a screwdriver, and a calm hand and patience; then we can start...
Power off your computer
Disconnect all cabling at the back of the computer. Maybe you want to note which cable goes where so that later it is easier for you to put back the cables.
Open your computer case (the one that is opposite of the motherboard.
Now you can either use a "digital camera" ro assist you; so you make pictures of the board configurations, or you can make drawings to guide you (You probably want to put a new motheroard into the PC so you also want to know where the cables will go right ???
Disconnect your cables from your motherboard that come from your power supply. Also disconnect the wires going to your drives ( CD-ROM, DVD) that come from the Power supply.
Now disconnect your Data cables ( IDE or SATA cables) that run from your CD-ROM / DVD and hard drives. Just remember their configeration.
Now, disconnect the other cables, mainly audio, cpu fan cable, chassis fan cable and audio drive through cables and any other cables attached to your MB.
Next up we have the removal of devices that are direclty attached to your MB. Remove the RAM (Do not touch the RAM on the chips, rather hold it at the sides), remove all add in PCI cards like network card,graphics card etc and put them in seperate anti-static containers
Now its time to get the proc: Remove the heatsink+fan by unscrewing it from the MB; there must be four screws around the MB. If you have removed the Heatsinkwithfan, you will see the proc. There must be either a little switch, a screw or lever to "release the proc" from its "socket" otherwise you will damage your proc and or your motherboard. If you have released the lever, you can remove the proc. lay it somewhere, so that its pins or chips lie down.
Check if there are addional devices that need to be removed.
Next, unscrew the MB from the casing, There should be about 6-12 screws on the MB.
All done: All you need to do now is remove the motherboard slowly from its rest, take it out and put it somewhere safe
take proc. out and check if you bent any pins when replacing it. make sure you installed it correctly. some motherboards wont boot if cooling fan is not connected to motherboard. make sure motherboard supports new proc.
