If your computer is running slower than usual, randomly freezes or restarts, or refuses to boot, see the Motherboard Has a Faulty Capacitor problem page for capacitor troubleshooting help.
Have you tried unplugging the power cable and shorting the physical pins on the board for the power switch? You could potentially just have a bad switch or one that isn't connected properly. Here's a link to the motherboard. Page 42 covers the front panel header, though I would review this manual in more depth. I'm seeing some DIP switches that I haven't seen on a computer in a while, so make sure you have those dialed in for stock speeds settings before attempting to boot and make changes. Have you attempted a full disassembly and reassembly with only the CPU, GPU, and RAM installed?
Picture # 5.... It seems that the "power" thing is crooked. I am new to things like this, but I think that could be part of the problem. And there is a lot of dust. Maybe try cleaning it?
"First: Close that PSU now. This is horribly dangerous, if you touch the wrong part and unload a capacitor you can kill yourself.
There is also a very good chance it wont post because there is no CPU cooler mounted. A CPU requires a specific amount of pressure to make contact with the socket.
Even if it would turn on, it would overheat within 20 seconds and shut down again. On older CPU's this can be fatal to the CPU.
So: Mount the Cooler, and make sure it fits properly (No wiggling). And make sure you use thermal paste."
I am currently buildimg a pc. When i plugged the 24 pin the fans were already spinning (even from gpu) and i got 2 red Led glowing (cpu led), then i plugged the 8 pin connector for cpu power. Now I’m getting a green Led, no sign of life. I’ve already tried to use the phisycal pins instead of the power button. Still not working.
