My computer won't POST, I get lights and fans, but no beeps and no display. I've had the rig about a year without any problems.
The phase leds are all on (green-yellow-red) and additional lights (green-yellow) are on next to the RAM slots.
I've tried each RAM stick individually and don't get a warning beep when none are installed.
I managed to isolate the problem to motherboard and CPU:
1. I breadboarded the mobo and pulled out everything but the PSU and CPU.
2. I replaced the Mugen with the Intel stock cooler and reseated the CPU.
3. The PSU manages to boot up my old PC so I don't think it's that.
In summary, the lights are on but nobody's home
I did overclock a little, but didn't try to max out (I can't remember the speed unfortunately)
Can't find your answer ? Ask !

Alright I am a bit late on this issue, Here goes green,yellow,red on the phase led's green representing low voltage on the voltage regulator,yellow being mildly overclocked YOU GOT TO REMEMBER YOU GOT ONE OF THE FASTEST BUILT TYPE BOARDS EVER PRODUCED GIGABYTE GO OC DOES THIS RING ANY BELLS.mildly I say which means watercooling yellow led. Then you said red on the phase AT THIS POINT YOU NEED TO HAVE A PHASE CHANGING SYSTEM TO COOL THAT MOTHERBOARD DOWN. In other words not so much voltage. Try to remove the cmos battery and try a fresh boot If you don't want to lose your data then buy a new hard drive,other wise buy a new motherboard of the exact brand and model.
