PC won't turn on help please!

Hey guys, I'm in a dilemma at the moment. My friend brought over a chasis so I could move all the components from my computer to the new chasis. When I moved everything, I plugged the 4-pin to the CPU and the atx power cable. I then connected the io port cables and it turned on. Then I took the io cables, unplugged them, moved some things and replugged the io cables and it wouldn't turn on. I followed the manual for the mobo and nothing. So I decided to switch everything back over to my computer chasis. I connected the io cables and nothing. My mobo's light switches on green when the power is on but nothing else. I have the Asus P8B75-M LE motherboard. I hace been at this for so many hours but nothing ...

  1. Hi,
    If leaving only CPU and CPU fan installed, both 24 and 4 pin power cables connected and starting the board, is the CPU fan spinning?
    If not, can you test different power supply?

    Hey, I did what you said and left only the CPU and CPU fan installed with the 24 and 4 pin cables connected but It wouldn't start. No response at all. I tried using a different power supply, and and when I went to click on the power button nothing happened. I'm running out on ideas...
  3. Then it looks like a motherboard issue (unless 2 faulty power supplies).
    Have you tried starting the board by shorting the 2 pins on the motherboard where the power button wires get connected (for ruling out a power switch issue)?

    No I haven't tried that? How would I do it though?
  5. Locate on te motherboard the system panel connector (where the reset, power buttons and HDD and power leds wires get connected to the motherboard).
    Identify the 2 pins correspondig to the power button (use the board's manual if not sure which).
    Use a screwdriver or similar for shortly connecting together the 2 pins for starting the board (it's what the power button does when pressed).

    do you mean the front panel connectors? Where you plug the front i/o wires to the motherboard?

    Yes.


    Okay, so now I located the pins the correspond to the power button. Now what do I do? Sorry it's just that I'm being way too cautious with this, but thanks for helping me though.
  8. The power button, when pressed actually connects together the 2 pins. Use a screwdriver and touch the 2 pins with it.

    Hey man it turns out that I removed the little plastic jumper from my motherboard where the CMOS pins are. I found the jumper and placed it back in and now it turns on. Thanks anyway for the help man I really appreciate it.
  10. I wouldn't have thought of it, although it's the second post i've read with a similar issue. I'll add it on my troubleshooting list.
    Good luck!
