Question PC won't start, only power supply and fans working??

[idler89]

Yestetday I came into my room and PC was running and monitor was off. I tried to move the mouse and press the keyboard to turn it back on, it didn't work. Than I tried to restart PC, nothing, than I held power button, still nothing. Than I finally turned it off on power supply switch. When I pressed power supply switch again it immediately turned on, which is weird, but only fans and power supply were working. No sound, no led lights on the front, power button not working. I tried to remove RAM, nothing. I tried to reset bios, nothing. I replaced power supply, still nothing. I'm out of ideas, does someone have any idea what's going on? Thanks.

I had exact same problem as you. Do you have POST code on your motherboard? What are your specs?
