  1. What happens when you push the power button?
    Have you connected the power button's plus and minus cables at the bottom-right of your motherboard?

    When I press the power button nothing turns on, not even the fans and I looked up my motherboard's manual to see where all the cables went and did it by that.
  3. I am not a expert at this, since i have only built two computers which both started at the first try.
    It sounds like the motherboard is not getting power, check if the 24-pin power cable is connected all the way until it locks in place.

    You probably know more than me anyway, so checked the 24-pin it was well in there and I'm really running out of things to check to be honest, is there anything else you can think of?
  5. Do like this: Take a flat screwdriver or a flat metal object, put it so that it touches both power + and power - where you normally plug the power button. Might be something wrong with the case power button.

    That didn't do anything either and I don't think there would be something wrong with the motherboard, it's brand new. Do you want to know my specs, maybe it may help?
  7. Yes, it may help.

    Motherboard: Asus p8z77-v
    PowerSupply: Corsair VS550 ATX
    GraphicsCard: Gigabyte GTX650
    CPU: I5 3570K
    Ram: 8GB
    There's some hard drives and cd drives
  9. Try this test for power supplies
    http://www.youtube.com/watch?v=5FWXgQSokF4
    Connect one or two fans to the molex connectors and check if spinning.
    If the power supply test is OK, then test again the motherboard, outside the case, with only CPU and CPU fan installed.
    Make sure that both 24 and 8 pin power cables are properly connected.
    See if the CPU fan is spinning when starting the board.
  10. Do you have the standoffs between the motherboard and the case? A friend of mine forgot about them and his computer did just like yours do.
  11. This is interesting.

    I tried the power supply and the power supply's fine, I just took out the motherboard and I'm putting it back in now seeing if that's makes any difference..

    Yes it's a couple of them, and you place them between the motherboard and the case so that the motherboard doesn't short circuit.
  15. Just because you didn't mention it and nobody has said anything about it yet, did you flip the switch on the power supply? I read another thread awhile ago where this was the problem.

    Yep. I've done that

    He tested the power supply and he claims that it is working so i assume he has it powered on.

    Yes, and I bet they felt really stupid after finding that out aha

    Yea I typed mine before he posted that but my phone is going slow today. Decided to leave it because it was still a possibility (though slim)

    Don't put it back. Put it on its box, connect the power supply and see if the CPU fan is spinning when starting the board.
    USe the scrediver method for starting the board.
  21. thanks y'all for your help, seems to be working now, Yaaaay :)
  22. lol so the Power Supply was switched off?
  23. THSNOTLEK said:

    No, i guess the motherboard's power took a short circuit through the case somehow.

    I think I talked too fast, it powered on went to the bios, I powered it down and haven't been able to turn it back on ever since and I actually unplugged everything graphics card, all the drives
  25. Take it outside the case and test for a while. Make sure it does work. Is there a CPU fan backplate installed?

    No there's no backplate

    Okay, done all you said and it's not even booting up this time, dunno why

  29. I say you throw that computer away and buy another one....

    The idea has crossed my mind but when you've spent at least a thousand dollars on something, you wouldn't want to do it
  31. Is the CPU fan spinning when starting the board?
  32. alexoiu said:

    No it's not doing anything anymore
  33. http://www.overclockers.com/forums/showthread.php?t=709083 It could be the MOBO there are at least 3-5 problems people have asked about.
  34. UPDATE: solved- i tested the RAM one at a time both were ok, then tried both (properly reseating them this time, doh!) and the red DRAM led turned off the POST splashed on screen and the keyboard, mouse and monitor got their signals.
  35. Any of those help?
  36. THSNOTLEK said:

    No not really, tried them all
  37. Its either your MOBO or your PSU. I can't find how many watts your system needs Maybe 500 is too low?

    I've got 550W tho
  39. Oh so confusing. Hate when computers don't work....

    Yeh it's a real pain!
  41. So you said it turned on but turned back off and won't turn back on?
  42. Also how is the cooling in there is it overheating?
  43. THSNOTLEK said:

    Yeh and that was about an hour ago
  44. Anyone got anything i could try out, that might make it work?
  45. For these problems, you generally want to start from bare bones to get to POST: just the motherboard, the 24 pin power, the 4 pin CPU power, CPU, cooler. No graphics card, no mouse, no keyboard, no monitor, no memory. Just try to get the thing to show signs of life. Make sure you have the motherboard on standoffs and that no screws fell onto it. Also make sure your CPU is properly installed and seated. Check your PSU cables for missing insulation.

    Do you have another mobo to test the PSU on?

    No I don't, I tested the psu with one of those vids on YouTube and it was working fine, it seems like my 24pin is not getting the signal through from the mobo and I've tried the screwdriver trick to turn it on too
